Cover frames - How do you turn your switches, buttons or sockets into a visual highlight? Are the standard models from the hardware store not individual enough for you? We'll show you how to combine colors, shapes and styles, sometimes across manufacturers. At eibabo® you will find a large selection of cover frames, cover plates, ring plates and central plates as well as intermediate frames from over 40 brand manufacturers.What are cover frames?The cover frame forms the outer ring of a socket, button, switch, controller, network socket or other insert. The manufacturers have adapted to the needs of their customers and produce switch programs with which you can determine the appearance yourself. Cover frames are available for individual inserts, but also for two to eight times. For example, combinations of switches, buttons, sockets and network sockets are possible. Choose between numerous designs, materials and the many variants for vertical or horizontal installation.Can frames and inserts from different switch series be combined?Combine the cover frames in different designs with inserts from other series and manufacturers. This allows you to design switches, sockets or other inserts with different cover frames in your living room in a highly individual way. Or set up your office workstation ergonomically and efficiently according to your ideas.What to look out for:Is the cover frame suitable for a round or square insert?What is the dimension of the inner diameter or cutout?Are the corners of the cutout rounded?Is the cutout square?Does the color of the insert match the color of the frame? PICTURE: Cover frame variants round and square, whiteThis results in the choice of the appropriate insert. Most manufacturers produce frames and cover frames with an inner cut-out of 55x55mm or 50x50mm. This enables you to exchange, combine or vary central inserts such as sockets or switches with frames, regardless of the manufacturer. Refer to the product description to find out whether the inside dimensions of the cover frame you have chosen fit the desired central insert. TIP:White is not the same as white. If you want to combine different white parts from different manufacturers, please make sure that the color and the surface are the same. Slight differences in color and surface gloss between white components quickly appear as incorrect colors. However, deviations do not pose a problem if two contrasting colors are intended to be combined.Are there also cover frames that do not match other series?Of course, there is nothing wrong with choosing a special range of switches from a specific supplier here in the shop. There are numerous cover frames and inserts that only fit the respective counterpart of the special series. Nevertheless, you have the opportunity for individual design, provided the series has color combinations.PICTURE: Cover frame variants - Busch Jaeger Impuls colouredSome manufacturers offer exclusive switch programs. These can be made of brass, stainless steel or brushed aluminium. Cover frames from these series are usually not compatible with other programs either.How do I mount a cover frame?In most cases, the cover frame is clamped behind the central plate (the plastic part of the insert) of the socket, switch or button. This is held securely by screwing the central plate to the insert. If you want to remove the frame, loosen the screw in the middle of the central plate and pull it off carefully. Now you can remove the frame. Please pay attention to your safety, because after removing the covers, the current-carrying contacts are exposed. When working with electricity, please always switch off the power supply beforehand and secure it against being switched on again.Hygienically cleanCentral plates and cover frames are often touched and should be cleaned regularly. Dirty plastic parts can be cleaned again in the dishwasher.Cover frames that are sensitive to heat or water (e.g. metal frames) should be carefully cleaned by hand. Before you begin assembly again, the clean parts must be absolutely dry. Place the frame behind the central plate and screw it to the insert.Do cover frames break easily?Cover frames and central plates are rarely subjected to greater loads. Only during assembly and disassembly is there a risk of damage, for example by overtightening the screw. In everyday life, the high-quality products from all major manufacturers have proven to be very robust. Benefit from our huge selection and the low prices for cover frames from ABB Stotz, Gira, Hager, Jung, Bachmann, Ekey (AT), Berker, Busch-Jaeger, Elso, CommScope, Corning, Eltako, Legrand, Merten, Rademacher or Telegärtner, Wisi, Peha, Siemens, SOMFY or Tehalit.

Surge protector - measur./control - Modern sensors, measuring devices and probes monitor and control complex and interdependent processes. Protect these operations from power surge failures. We will introduce you to different MSR surge arresters and support you in your purchase decision.   Automated processes intervene deeply in a building management system or in production processes. As a result, a very high degree of availability of the determined and transmitted measurement data and control signals is required. Surge protection devices make a significant contribution to safeguarding the function of this technology in the event of voltage peaks of all kinds. Depending on the risk potential and the level of protection required, select the surge protection devices that are right for you and combine them with other protective circuits if necessary. Image: Dehn DPA-M-CLE-RJ45B-48 surge arrester What are MSR surge arresters? MSR stands for measurement technology, control technology and regulation technology. MSR technology is used in particular within modern bus systems and telecommunications systems. Private and industrial areas of application are: air conditioning and refrigeration systems heating systems and ventilation systems the field of water technology and waste water technology the electronics sector and smart home   The MSR overvoltage protection devices are used in electrical engineering to limit and divert overvoltages in electrical lines. Particularly sensitive measuring devices and control devices can be damaged by overvoltages, incorrect measurement data can be determined and incorrect control signals can be sent. But how does the overvoltage come about? Lightning strikes, short circuits, electrostatic discharges or switching operations by the network operator generate mains voltages which are well above the normal value of 230V in Germany. The consequences of such an event depend on the level and duration of the overvoltage and the speed of the voltage pulse.   The MSR surge arresters (Surge Protective Devices SPD) are usually installed directly in front of the signal inputs of the measuring devices and control devices to be protected. In the context of a three-stage overvoltage protection, these represent the so-called fine protection (type 3). What is measurement technology, control technology and regulation technology? MSR technology records a wide variety of situations and states within automated processes. Depending on the type and area of application, individual parameters are determined using different measurement methods. Typical measured variables are temperature, pressure, speed, humidity or chemical composition. These measured variables are converted into electrical signals such as current, voltage or resistance and serve as the basis for triggering logical actions. How is an MSR surge protection constructed? A general overvoltage protection is usually structured in three stages and is part of the internal lightning protection of a building. There are different requirement classes for overvoltage protection devices. We distinguish between type 1 (rough protection), type 2 (medium protection) or type 3 (fine protection). When selecting suitable protective devices, the type of possible fault and the type of device to be protected are considered. This results in a combination of different surge arresters adapted to the respective needs, which together ensure coarse, medium and fine protection.   Type 1 coarse protection devices are used to divert high lightning currents. These reduce the residual voltage of an overvoltage to a level between 6000 volts and 1300 volts. Type 1 devices are usually switched before the house installation. This means that the high lightning current cannot even reach the house distribution system.   Type 2 devices provide medium protection. They reduce the residual lightning voltage to values between 2000 volts and 600 volts. They are installed, for example, in the sub-distributors of individual apartments or parts of buildings. Medium protection devices also limit dangerous transient overvoltages. These are caused by the switching of transformers, circuit breakers, motors or inductive loads. Already knew? Surge arresters are not disposable fuses. The devices can ensure reliable protection over a long period of time and do not need to be replaced after they have been triggered.   The Type 3 overvoltage protection further reduces the remaining overvoltage. These devices provide fine protection and protect against voltages up to a level of 1000 volts AC or 1500 volts DC. The MSR surge arresters available in this eibabo® catalog belong to this category. Are MSR Surge Arresters Really Necessary? Whether special protective measures against overvoltage are required for your MSR devices must be considered individually for each installation. Estimate the risk objectively, taking into account the probability of overvoltages and overcurrents. Base this assessment on all existing parts of your protective measures against overvoltages. Include the risk of electromagnetic phenomena such as lightning discharges or earth potential rises in your considerations. Ultimately, you should achieve reliable protection for your entire system. Please consider the organizational and financial consequences that the failure of important measurement and control devices would have for your operational processes. When should I choose an MSR surge arrester? Power connections and data lines are an integral part of our everyday lives. Stable signal transmissions are essential for smooth business operations, and not just in industrial or commercial environments. Our high-tech lifestyle also demands reliable connectivity. If you recognize yourself in any of the following questions and answers, then MSR surge arresters are for you.   Do you value security? Security devices such as alarm systems, door intercom systems, access controls and emergency call devices only offer complete protection if the power supply, the monitoring sensors and the data lines work permanently. MSR surge arresters protect those systems that ensure your protection.   You don't want to do without the amenities of modern living comfort? A lot of planning, work and money goes into modern smart home installations. The automatic control of temperatures, shutters or multimedia applications enable a comfortable living environment. With MSR surge arresters, this convenience is maintained even in the event of an overvoltage.   TIP:Investing in reliable surge protection is usually less expensive than replacing, repairing, and installing new equipment.   Would you like to secure your independence? The production of your own electricity is becoming more important every year. Modern and environmentally friendly mobility solutions and heating systems rely on electricity from your own photovoltaic system. The efficient use and storage of electricity requires complex control devices. With an MSR surge arrester, you can protect this expensive technology from surge damage. You retain your independence from energy suppliers.   Do you want to protect investments and preserve property? Real estate is an investment and provision in one. The technical equipment of a building has a significant influence on its value. By using MSR surge arresters, you not only get the building services, but also your old-age provision.   In our catalog you will always find the right surge arrester tailored to your requirements for your individual device variants. You get the best quality at low prices.

Wide span cable tray - Are you looking for a stable cable support system? Do you have larger spans to bridge and want to ensure that the weight of the cables is carried safely? Your eibabo® shop offers you a huge range of cable support systems from well-known manufacturers at the best prices. With numerous modules you can meet almost all architectural requirements and lay cables and lines quickly, clearly and inexpensively. In this catalog you will find the product group 'Cable trays and wide-span cable trays'.What are cable support systems?With cable carrier systems, you can lay cables and lines vertically and horizontally through rooms, basements, production halls and across floors. In contrast to electrical installation conduits, the systems accommodate massive cable bundles and are therefore suitable for complex commercial systems and industrial applications. You can use this, for example, to lay the power supply for your building. Or you can use it to create measuring systems, control systems or other wired data transmissions for your system. The modular design ensures maximum flexibility combined with stability, security and cost efficiency.Image: OBO Bettermann RKSM620 cable trayWhat are wide span cable trays?Wide-span cable trays are part of cable carrier systems. These form long, rigid and rectilinear structures for laying electrical cables, conduits and cable ducts. Cable trays are typically made of galvanized steel, stainless steel or aluminium. There are also non-metallic cable trays. These are made of glass fiber reinforced plastic. The different cable tray types include:Metal cable trays (perforated, slotted and in ladder form)Small metal ducts (perforated, unperforated)Cable trays made of non-metallic material (perforated, slotted and in ladder form)Small ducts made of non-metallic material (perforated, unperforated)Metal and non-metallic cable trays (unperforated)Metal wire mesh cable trays Why are some cable trays perforated and others not?There are perforated and unperforated cable trays. Some cable trays consist 'only' of a wire mesh. The difference lies in the different possible uses. In most cases, open cable trays are used. These are in the form of ladders with rungs or a base, and side parts are provided with round or oblong holes. The holes have different functions:ventilationCurrent-carrying cables and lines can generate heat. The removal of excess heat is a safety feature, especially when these are laid in a bundle.attachmentCable ties and other fastening systems can be pulled through the holes. This allows the cables and lines to be sorted and fixed. In addition, fastening systems such as ropes, hanging brackets or support arms are connected to the channels through the holes.weight reductionMetal cable trays are solid. Cables and wires can also be very heavy. Larger installations often reach a high weight as a result. Perforated material is lighter and simplifies assembly.junctionIf individual cables and wires need to be routed out of the gutter, this can be done, for example, down through one of the larger holes.water permeabilitySprinkler systems are installed in many areas for safety reasons. In an emergency, the water can drain through the holes in the cable trays. TIP:With wide-span cable trays, you can bridge a span of up to 3 meters. In contrast, the unperforated cable trays are installed at other locations. Closed systems are used for:Rooms with increased pollutionIn a dusty environment, the laid cables and lines remain clean and can be replaced, checked or repaired more easily in an emergency. Additional gutter covers are used in these environments.Electromagnetic shieldingClosed cable trays have a shielding effect. The influence of the cables on the environment (or vice versa) is significantly reduced through the use of unperforated cable trays.What does suitability for functional integrity mean?In the product descriptions of the cable support systems, some information on functional integrity is stored. This information is used to help you assess the suitability of each system for specific locations. Fire safety is an important issue in private, commercial, industrial and municipal buildings. There are special requirements for safety-relevant areas, also for the supporting devices of the electrical installation. Functional integrity describes how long the system must remain functional in the event of a fire.Functional integrity of 30 minutes (E30) is required for electrical systems used to evacuate people and animals from a burning building. These arefire alarm systemsSystems for alerting and issuing instructionsSecurity lighting and backup power lightingpassenger elevatorsSmoke and heat extraction systems Functional integrity of 60 or 90 minutes (E60 and E90) is necessary for the fire brigade to fight fires effectively and for complex evacuations. For example, it applies toWater pressure booster systems for the supply of extinguishing waterAutomatic extinguishing systemsFire brigade lifts and bed lifts (in hospitals)Ventilation systems and smoke protection pressure systems of safety stairwellsElevator shafts and machine rooms In these applications, use tested cable support systems that guarantee functional integrity of up to 90 minutes, depending on the requirements.With what weight can cable trays be loaded?When choosing the right cable tray or the optimal cable support system, its resilience is crucial. The carrying capacity must correspond to the expected cable weight. TIP:Calculate a reserve of 10% for possible subsequent installations when considering the load-bearing capacity. Approximately 15 kg per meter and per 10 cm channel width apply as a guideline for the load capacity. With a channel width of 30 cm, for example, this results in a load-bearing capacity of around 45 kg per meter. With a channel width of 60 cm, the value increases to 90 kg per meter. Alternatively, look at the manufacturer's product specification or use the formula of DIN VDE 0639 T1 to calculate the maximum permissible cable load.What accessories are available for wide-span cable trays?At eibabo® you will find all the components you need to route cables and lines individually through your building. Examples of suitable accessories and add-on modules for wide-span cable trays are:Gutter connectors, gutter bends, angle brackets and end piecesTees, crosses, branch pieces and reducersCable rakes, base plates, hanging brackets, coversSupport arms, cable ladders and fastening material We carry complete systems from all leading manufacturers, including OBO Bettermann, Niedax, Unex, Pflitsch, Tehalit, Legrand Cablofil and many more.

Interface converter - What can you do if the connection points on a particular device do not match the interfaces on another device? However, your installation project provides for a connection between the two devices. No problem, then simply use the eibabo interface converters. Such a device converts the signals from your device and bus connections so that they are compatible with the plugs or sockets of the other device. Furthermore, an interface converter transfers the data from one transmission protocol to the other and vice versa. If this cannot be done automatically one-to-one, there is the possibility that you as the user can still configure or program the interface converter. Please note that not all existing interfaces can be universally changed. There are operating modes in which conversion to one another is not possible. If you are unsure or have any questions, please contact our competent eibabo customer service.Catalogue content:In this eibabo® catalogue Data and telecommunication > Interface converter you will find items from the following product groups:Item overview:20mA (current loop) interface20mA interfaceArea couplerArea couplingBidirectional converterCommand deviceConversion moduleConverterCurrent matchingData converterFiber optic moduleInterface cableInterface converterInterface technologyManual control levelPlug-in modulePROFIBUS interfaceRS-232 interfaceRS-422 interfaceRS-485 interfaceSignaling deviceSystem deviceTransmission converterTTL level interfaceUSB interfaceValve positionsVoltage converterVoltage transducerfrom the following manufacturers:Manufacturer overview catalogue Interface converter:CeagEFB-ElektronikFlukeHirschmannJumoMetzMurrelektronikPepperl + FuchsPhoenixSiemensTechniSatWAGOWeidmüller
Distributor-timer - digital - Don't you also think that many electrical consumers don't have to be in operation all day? Would you like to save costs and conserve resources? This is possible with timers for the control cabinet. Find out here which functions digital distribution time switches can take on and which special features you should pay attention to when buying.At eibabo® you will find the right digital distributor time switch for installation in the electrical distribution board. We carry a large selection of Astro timers, weekly timers and yearly timers. Manufacturers of high-quality devices include Hager, Finder, ABL Sursum, Theben, ABB, Stotz S&J, Legrand (BT), Grässlin, Eltako and Schneider Electric. In the following text we will go into the individual variants in more detail.What are distribution timers?A time switch for the junction box is an electronic or mechanical device that switches electrical consumers on a time-controlled basis. These can be switched on and off without having to flip the switch yourself. This can be useful in private households as well as in commercial companies and in the industrial sector. The purposes of the distributor time switches include, among other things, the automatic switching on and off of lighting systems or the control of fixed house installations such as heating, ventilation, lawn sprinklers and air conditioning units. This not only saves you time, but also money.NoticeDistribution time switches are often offered in grid dimensions (pitch units). Depending on the equipment, such a device requires one to four modular widths in the control cabinet.The advantages of a timer are therefore obvious: electricity costs can be reduced effectively through the targeted control of your electrical devices. At the same time, you have the option of making your home less attractive to burglars, for example by simulating your presence using optionally available random functions.You can also get digital or analogue timers for the socket in another catalog from the eibabo® shop. Their function is comparable to that of the distributor time switches. However, the area of application extends to 'mobile' devices that are not permanently installed. These include Christmas lights, aquarium technology or decorative items such as fountains.What functions do distribution timers offer?A high-quality distributor time switch offers numerous functions and programs for the individual setting of the switching cycles. These include:60 min program / 24 h programWeekly program / annual programAutomatic summer/winter time changeoverholiday programimpulse programcycle programastro programrandom programPermanent switching ON/OFFexpiration timerhour meter Image: Theben TR 644 top2 RC distribution time switchWhat is the difference between each type of timer?We often come across terms such as astro timers, weekly timers or yearly timers. With regard to a purchase decision, the question then arises as to whether there are significant differences between these models. The basic function is the same for all models. The differences lie in the detail and the setting options of the individual variants. The astro function of a timer adjusts the switching times daily to the seasonally changing length of the day. In other words: When the days get longer in spring, the device switches on a little later every evening and a little earlier every morning. This process is calculated electronically and does not require a brightness sensor, for example, which would otherwise have to give the command to switch the light on or off. With a weekly timer, you can set individual switching times for each day of the week. In contrast, the function of a very simple time switch is limited to setting switching cycles within 24 hours.Already knew?Modern timers have a powerful power reserve. In the event of a power failure, this ensures the function of the timer for up to 10 more years.The annual time switch offers even more extensive functions. This means that different switching times can be provided for each calendar day and vacations and public holidays can be taken into account.Do distribution timers require a separate power supply?Digital timers always require energy to operate. As a rule, a distribution time switch is clamped onto the DIN rail of the control cabinet and supplied with mains voltage via an integrated power pack. Time switches that are exclusively battery operated are rare. These are typically analogue variants, which are used, for example, as 'door openers' in stables when there is no electricity.Is a digital timer always better than an analogue model?An analog timer works mechanically, a digital timer works electronically. Whether one or the other variant is more suitable for you depends on your requirements for the device. Mechanical timers usually have a higher-level switch with which you can switch the device off completely, switch it on permanently or switch it to switching mode. Switch buttons arranged in a circle represent the daily routine. There are usually 48 buttons and each button stands for half an hour. Activate or deactivate the corresponding switching period by pressing or pulling out. Compared to analog timers, digital timers offer significantly more setting options and functions. In contrast to mechanical timers, you can usually set several switching programs down to the minute over days or weeks. The distribution timer is operated using buttons and a display. TIP:If you want to control more than one device with the distribution timer, choose a model with the appropriate number of channels. This saves a lot of space in the control cabinet. Times and switching programs are clearly shown on the display. In terms of accuracy and functionality, a digital time switch is clearly superior to the analogue version. However, it requires a certain learning phase to understand the technology and set switching programs. If you only need 'rough' and daily recurring switching processes, analogue time switches are still a good alternative. These are set up and ready to use in just a few seconds.Can distributor time switches be programmed using an app or externally?There are distributor time switches that have Bluetooth and can be configured using an app. This allows you to display and change the switching states via smartphone or tablet computer. The prerequisite is the coupling between the input devices and timers within a network. Another way of programming the switching times is to use manufacturer-specific software. You can transfer the switching information to a special memory card via the USB interface of your computer. The memory card can then be connected to the time switch on the construction site/in the switch cabinet and the switching data can be loaded into the switch and vice versa.Doesn't a distribution timer consume more electricity than it saves?If the focus is on switching a consumer (e.g. the lighting) on and off, a distribution time switch is of course useful. As a rule, active end devices consume significantly more power than a timer. The question asked above relates to switching off a device that would otherwise run in standby mode for hours.To answer this question, a distinction must be made between an analogue and a digital time switch. An analogue model is less complex and usually has an output of less than 1 watt. With an electricity price of 40 cents per kilowatt hour, for example, the consumption costs are around 1 cent per day with 24 hours. With a digital timer, you have to assume around 2 watts and thus calculate electricity costs of 2 cents per day. In this calculation example, the investment costs for one or more time switches should also be taken into account.You can now compare this with the standby power consumption of your devices. This essentially depends on the type, age and number of devices. Old devices with displays consume more power in standby than modern electronics with only one control LED. A mix of new and old devices in the household currently results in an average consumption of 1 to 2 watts per device. If you need a separate timer for each electrical device, using them to save standby power is therefore not economical. The situation is somewhat different with distribution time switches, which can switch several devices or machines with a high standby current at the same time. This may save you on standby electricity costs, although this is not the primary reason for using a timer in these cases either. TIP:Pay attention to the shortest switching time of the device if you want to switch short intervals. Some devices only switch every minute and only a few devices switch every second or even faster. An example: If you have a terrarium with a sprinkler system, the nozzles should usually only spray for a few seconds. This is to maintain high humidity. Prolonged spraying may flood facility and animals.  Catalogue content:In this eibabo® catalogue Devices for distribution board- / surface mounting > Digital time switch for distribution board you will find items from the following product groups:Item overview:Astro timerBuilt-in timerDaily timerDigital timerDistribution timerEnergy efficientExpansion moduleInstallation timerJunction boxLighting controlLocation dependentPosition dataPower reserveProgram clockQuartz timerSeries installationTimerTimer moduleTimersUniversal timerWeekly programWeekly timerYear time switchfrom the following manufacturers:Manufacturer overview catalogue Distributor-timer - digital:ABBDoepkeEatonEltakoFinderHagerHamaLegrand BticinoSchneider ElectricSiemensTheben
Ballast - If you equip your building with fluorescent tubes, high-intensity gas discharge lamps or linear plug-and-play LED lighting, you depend on ballasts. But which one is right for your application? We clarify. When you use the optimal ballast, you create a cost-effective and energy-efficient lighting solution that also gives you enhanced control over the amount of light produced in your space. Find the ballasts you need for lights and lighting systems easily at eibabo® in the extensive online range. In addition to ballasts in a wide variety of designs (electronic, DALI, KL/LL, EVG and many more), you will also find Powertronic devices and Quicktronic devices, QT-FIT ballasts, warm start devices as well as ignition devices and stabilization devices.What is a ballast?In fluorescent lighting, the ballast controls the power supply to the lamps. It provides sufficient starting voltage to start the lamps. Without a ballast, a fluorescent lamp connected directly to the mains voltage would quickly and uncontrollably increase the power consumption. Within a second the lamp would overheat and burn out. When the lamp is started, the ballast provides a brief high-voltage phase to build up an arc between the two lamp electrodes and start the ionization of the gas. This makes the gas inside the lamp electrically conductive. Once the arc is established, the ballast reduces the voltage. From that moment on, it serves to regulate the electric current in order to guarantee a constant light output.Please noteFluorescent tubes and gas discharge lamps have a negative, differential resistance during operation. As a result, as the current increases, there is a voltage drop across the lamp. For this reason, never connect gas discharge lamps directly to a voltage source.In order to achieve the full rated light output and maximum service life of a fluorescent lamp, the output characteristics of a ballast must exactly match the electrical requirements of the lamps being operated. Ballasts are typically designed in such a way that they operate a certain number of a certain lamp type with the necessary voltage. These are therefore also your primary selection criteria for the purchase of a ballast. So in order to find a suitable ballast that is compatible with a specific lamp, you should know the lamp type, lamp quantity and mains voltage.Why do only certain lamps need a ballast?Classic incandescent lamps and halogen lamps do not require ballasts. This is because the current flows through a filament. This filament resists the current, causing it to heat up and glow. It takes a lot of heat to illuminate a room bright enough. Therefore, the majority of this energy is used to generate heat and not light. This makes conventional incandescent bulbs very inefficient. LED lights also typically do not require ballasts. Here, LED power supplies and LED drivers regulate the current and voltage. The operation of fluorescent lamps and gas discharge lamps is slightly different. These are filled with gases and emit photons when charged with electricity. photonsPhotons are basic subatomic particles or waves that carry the electromagnetic force. In short: they are light particles. So in these lamps there is no filament to resist or regulate the electricity. The ballast is required for this.What types of ballasts are there?There are many different types of ballasts. The choice depends on the conditions in which your lighting is working. We distinguish between magnetic (conventional) ballasts and electronic ballasts.Conventional ballasts are the older technology and used to be responsible for flickering on start-up and lamp buzzing. Conventional ballasts have not been used since 2005 due to their low energy efficiency and high power losses of up to 20%.Nowadays, most fluorescent tubes and gas discharge lamps are operated with electronic ballasts. Electronic ballasts can emit multiple electrical frequencies without changing the input voltage. This eliminates any flickering and humming. These ballasts are available with different starting technologies:Quick StartInstant startprogrammed start Instant start ballasts switch the light on the quickest. However, these are designed for longer switching cycles. Frequent turning on and off can shorten lamp life. The devices are called instant starters because they immediately send a high voltage through the lamp to start the cathodes. Typically, instant start ballasts use slightly less power per lamp than quick start ballasts. Instant start lamps work reliably down to 0 °C.Already knew?Ballasts are also called 'ballast' in international usage. This designation is derived from their properties. Just as ballast stabilizes a ship's hull, a ballast stabilizes the power supply to a lightbulb or lamp.The ballasts work more slowly for both programmed start and quick start. However, these do not have the deleterious effects of an instant start ballast when switched on and off more frequently. The ballasts measure the temperature of the tube cathodes and preheat them. This makes starting easier and the lamp switches on immediately as soon as the light switch is pressed. However, quick-start ballasts also have disadvantages:The devices are not very energy efficient.Lamps connected to quick start ballasts do not turn on reliably at very low temperatures. Programmed start ballasts are typically coupled with occupancy sensors or motion sensors and maximize the number of lamp start cycles while maintaining energy efficiency. If you have high-traffic spaces in your building that experience multiple on-off cycles throughout the day, a programmed start ballast may be the best alternative for your lighting. Ballasts with programmed start are reliable even at low temperatures.When should I replace my ballast?Although replacement is not common, after a few years changes in ballast performance can become noticeable. If your lamps seem to be fading, humming, flickering or changing colour, it may be time to change the ballast.Image: Ledvance PTi 150/220-240 ballastAre ballasts equipped with a DALI interface?If you want to implement digital light control as part of your building automation, you may use the DALI system.What is DALI?DALI is the abbreviation for Digital Addressable Lighting Interface. It represents a programmable, digital interface for lighting scenarios including electronic ballasts. DALI is a protocol for light control in building automation, but not a bus system.DALI is suitable both for light control in individual rooms and for lighting scenarios in networked building management. As a rule, the modern electronic ballasts from most manufacturers are equipped with DALI interfaces. These interfaces establish direct communication between a control device and the lamps to be controlled. The communication between the control unit and the up to 64 connected devices takes place via a bidirectional two-wire line, so that information is transmitted both from the control unit to the lamps and vice versa. Programming the system is easy and hassle-free. For example, integration into a higher-level KNX building management system is possible via gateways.We offer you a large selection of ballasts from all well-known manufacturers such as ABB Stotz, Arclite, Ceag Notlichtsysteme, Houben, LEDVANCE as well as Philips lamps, Schuch Licht, Waldmann and Watt24.  Catalogue content:In this eibabo® catalogue Light control > Ballast you will find items from the following product groups:Item overview:BallastControl gearControl unitControllersDischarge lampFluorescent lampFluorescent lampsHeadlight bulbLightingLuminaire control gearOperating devicesPower supplyfrom the following manufacturers:Manufacturer overview catalogue Ballast:ABBArcliteCeagHoubenLEDVANCEPhilips LichtScharnberger+Has.SchuchSignify LampenSitecoZumtobel
