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.

Fuse terminal - Are you looking for high-quality and space-saving fuse terminals for your control cabinet? Are terminal blocks the same as fuse blocks? Here you can find out for which use the different fuse terminals are suitable. In the eibabo® technology store, you can obtain fuse clamps inexpensively and in large quantities from all well-known manufacturers. Shipping is worldwide. Fuse terminals are among the most important components in a control cabinet and have several functions. The terminals are snapped onto the top-hat rail of the control cabinet and form the connection between the distribution level and the installation level.What is the difference between fuse terminals and terminal blocks?The terminal block is a feed-through connection for one or more cables in the control cabinet. Depending on the application, it may be beneficial to protect a pass-through connection with a fuse. Fuse terminals consist of a base that takes on the function of the classic terminal block. A fuse is used in an additional fuse link carrier. The fuses may vary depending on the model and use case. Some variants have permanently installed circuit breakers. A fuse terminal block is therefore a terminal block with a separate fuse.Why are fuse terminals one of the most important components in the control cabinet?A large number of cables and lines arrive in a control cabinet. Depending on the complexity of the system, this can be several hundred pieces. These cables and lines are often very rigid and have a large cross-section. A direct connection to the respective fuses, actuators or other devices would therefore be very difficult. At this point, terminal blocks with and without fuses are used. The cables and lines arriving in the control cabinet are first clearly laid out on the terminals. The individual flexible wires can now be routed from the terminals to the respective devices in the control cabinet. This flexibility offers advantages during installation.Image: Wago 281-611 fuse terminalEach connection now established has a specific function. This function is usually defined in a circuit diagram. Even after the control cabinet has been installed, the individual functions must remain traceable. A good overview of the system should be ensured for later extensions, change requests and maintenance work. If you would like to make changes after a while, these can now be done very easily by changing the individual wires. The handling of the rigid supply lines is therefore no longer necessary.You can only connect two wires to many modular installation devices. Here, too, the clamps play to their advantage. If, for example, you have planned several cables for a modular installation device, you can provide these with clear jumpers on the fuse terminals. Control work and measurements can also be carried out very conveniently directly on the terminals. Relocating lines and troubleshooting are made much easier.The safety clamps in detailFuse clamps can be constructed somewhat differently depending on the manufacturer. It is divided into single-level terminals and multi-level terminals. You can only connect one incoming and one outgoing line in the single-deck terminal. Several lines can be connected in multi-level terminals. For example, use a three-tier terminal for a cable with three wires. In this way you connect the protective conductor as well as the L line and the N line. This saves a lot of space and is mainly used in the private environment and in the smart home area. It is usual for the protective conductor contact to be made directly by the clamp connection with the top-hat rail. Other models have a connection point for a protective conductor.Another distinguishing feature is the different ways of attaching a cable. With a screw terminal, the respective wire is attached to the terminal using a classic screw connection. That's safe, but more time consuming. A spring-loaded terminal makes the electrical contact using a mechanical spring. The spring consists of a bent copper contact with a hole. The contact is clamped with a pointed tool and the conductor can be inserted. If you remove the clamping tool, the spring is relieved and the conductor gets stuck.Good to knowFuse clamps are suitable for fastening solid conductors and flexible strands. Both variants are permitted. The use of ferrules makes handling flexible wires easier, as they do not accidentally fan out.There is usually a pressure point for releasing this clamping connection, which can be pressed with a screwdriver or another narrow object. If you use particularly thin wires, insulation displacement terminals can be used. With these, contact is made through a small cut through the insulation.Cables and wires are selected in different cross-sections depending on their function and area of application. This affects the selection of the appropriate fuse terminal. There are suitable fuse terminals for the common cable cross-sections. Which cross-sections are suitable in each case is indicated directly on the terminal. Fuse terminals typically offer the option of bridging the L conductor and the N conductor using several terminal blocks, sometimes on different levels. The matching cross bridges are also available here in the shop. well thought outSome terminals offer fields for labeling. Use this option to keep track of the installation at all times. In addition, a distinction is made between fuse terminals in the design of the neutral conductor contact. Models marked 'NT' have special contacts for connection to an N busbar. When using a busbar, you need a clamp for the infeed as well as support blocks for secure fixing at the beginning and end of the busbar. When using 5-wire cables, you can also use multi-level terminals to connect the phase conductors.What does push-in connection mean for a fuse terminal block?A distinction is currently made between fuse terminals with three connection variants. These are the screw connection, the spring-cage connection and the push-in connection. Which connection variant you choose depends on the area of application, the costs and the expected time savings during installation. The push-in connection is the latest of these three variants. This is similar to the tension spring connection. As with the tension spring, a spring presses against the insulated conductor. The connection is therefore vibration-proof and maintenance-free. In contrast to the tension spring connection, the advantage is the tool-free installation. The wire is simply inserted into the terminal and a spring automatically locks. A standard screwdriver is sufficient to loosen the connection. This means that wiring can be carried out in a significantly shorter time. This applies in particular to cores with solid conductors. Wires with flexible conductors can also be fixed with this method using wire end sleeves. TIP:Please use square crimped ferrules for this. These offer more surface area for the spring to open. Front crimping pliers with square crimping are particularly suitable for working in hard-to-reach places and tight spaces. Small gauge conductors may not be strong enough to open the spring. Here the support of the spring opening with a screwdriver is necessary.Are there other accessories for fuse terminals?Additional accessories are available for most fuse terminals. These include the cross-bridges and busbars already mentioned, test plugs, fuses, separator plates, end plates, feeds or end blocks.Why are fuse terminals open on one side?The available space in the control cabinet is specified in modular widths (HP). These provide information about the capacity of a control cabinet. Fuse clamps are not manufactured according to this grid dimension, but as narrow as possible. The narrower a terminal, the more terminals can be installed on a specific area of the DIN rail. Since fuse terminals are typically mounted directly next to each other on the DIN rail, there is no risk of touching the contacts on the open sides. Without a side cover, a terminal is narrower. A cover is only attached to the last terminal in a row.Are there fuse terminals with a defect indicator?Some models show defects. For example, some fuse terminals have an integrated LED, which is powered by the current present. If there is a defect, the LED does not light up and the installer can quickly localize the problem.

Electricity meters - Have you always wanted to know how much energy individual devices in your household consume? This catalog from the eibabo® shop offers you the right measuring instruments for this. Here you can get high-quality electricity meters and many other meters at top conditions. In our modern home we use numerous electrical devices. In addition to lamps, washing machines and refrigerators, media technology is a major energy consumer. Televisions, computers, chargers for smartphones and building automation are powered by electrical energy. Although some of these devices also help save electricity, it is interesting to know how much energy they actually use.What are electricity meters?Electricity meters are devices for displaying electricity consumption or energy consumption in electrical systems. AC induction meters are predominantly used in households, which directly display the consumed kilowatt hours. To find out how high your energy consumption is in a certain period of time, you need to take two measurements. Subtract the value of the second measurement from the value of the first measurement.Image: ABB B23 113-100 three-phase meter M-BusWhat types of electricity meters are there?There are two main types of electricity meters. These are used by the utility companies. On the one hand there are the electromechanical meters and on the other hand the so-called intelligent meters or smart meters. If you operate a solar system and feed electricity into the grid, you need a third type of meter, the bidirectional meter. These measure the current drawn and the current fed in. As a rule, you have little influence on the electricity meters that come from your energy supplier. These are installed where the power lines enter your building. This catalog is about electricity meters, which you can also install. This allows the consumption of a specific section of your installation or the consumption of an individual end device to be measured.How is an electromechanical meter constructed?Electromechanical induction meters are widely used and can be found in many homes. These contain an electrically conductive, non-magnetic, rotatable 'Ferraris disc'. The disk is driven by the interaction of magnetic fields generated by two electromagnets.Magnet 1 is powered by the current from the incoming power linesMagnet 2 is powered by the current demanded by the building's electrical circuits The rotation of the disk is slowed down by two permanent magnets, which exert a proportional opposing force. The aluminum disc drives a scrolling mechanism that displays kilowatt hours or fractions thereof.How does a smart meter work?Electronic electricity meters have been on the market for several years. The current standard for electronic electricity meters are digital electricity meters and so-called smart meters. These work in a similar way to electromechanical electricity meters. Instead of mechanical moving parts, they contain a battery and a communication chip. The chip sends meter readings wirelessly to a collection point. This happens several times a day depending on the time of day. The data is usually transmitted to the electricity supplier every quarter of an hour via power lines, mobile communications or high-frequency networks. Already knew?The chip is also known as an encoder or ERT device. This uses the same frequency as many cordless phones. However, the device is designed to avoid interference. The battery in the communication chip in digital electricity meters is designed for a service life of 15 to 20 years.What are the advantages of measuring with an electronic electricity meter?With an electronic electricity meter, you can not only determine how much energy you use, but also when. At first glance, this may be less important additional information. But knowing exactly when and how much electricity you are using can save you a lot of money. Electricity prices vary throughout the day. When demand is high, electricity costs more than when demand is low. Constantly rising energy costs are leading to deregulation of the electricity markets. In the future, utilities could offer electricity tariffs that bill for the electricity provided based on the time of use. This would be a significantly fairer billing method than the current variant, which is based on average costs.smart gridSmart grids are intelligent power networks that take generation, storage and consumption into account. This allows fluctuations in power in the network to be compensated. Networking and coordination is carried out using modern technologies and decentralized energy management systems.Smart meters can also be read remotely. Utility companies thus save operating costs and working time. Electronic electricity meters are therefore an essential part of the so-called smart grid. The devices help you to question your habits and save money if you use your electricity off-peak. Think of buying an electronic electricity meter as an investment in your future.How do I find the right electricity meter?Modern electricity meters can be used to display electricity consumption in real time. Especially in the KNX area, intelligent electricity meters offer many advantages. These support you with load management within your installation and with the monitoring of services and end devices. This saves you money and time because you can make adjustments according to your consumption profile. The use of data loggers or programmable logic controllers makes it easier to display, control, analyze and monitor the data. You can integrate models with a KNX interface directly into your building automation system using Engineering Tool Software (ETS). But which things are still important when buying?number of phasesWhen choosing an electricity meter, please consider how many phases are required. The most common models are single-phase or three-phase. If your current system that you are getting your data from is single phase, you will need a single phase electricity meter. If the electrical system is three-phase, use a three-phase electricity meter. As a rule, the devices can be mounted on a DIN rail. The measurement is carried out flexibly for various performance parameters such as:True RMS Voltage (Vrms)True RMS Current (Irms)Active power (kW)Active energy (kWh)Apparent Power (kVA)Apparent energy (kVAh)Reactive Power (kVAR)Reactive energy (kVARh)Power Factor (PF)frequency The devices can be used both on the primary side of the low voltage and on the secondary side of the medium voltage and high voltage.The ampPay attention to how many amps you need for the system. Commonly, smart electricity meters support 60 amps, 100 amps, and 200 amps. The right choice depends on your power system. Using a 100A electricity meter for a system that requires 200A would be impractical.Bus systems and networksIntelligent electricity meters communicate via various media and protocols. Please determine in advance which communication protocols will be used. Well-known fieldbus systems are AS-Interface, CAN, CANopen, M-Bus, EtherCAT and others.
