Potentiometer command device - We all know potentiometers. These are devices that take a certain input voltage and pass it on to a circuit in an individually adjustable amount. It sounds abstract, but it's actually quite simple. For example, the volume controls on older radios are rotary potentiometers. If you want to change the volume, you guide a so-called grinder over a resistance body through the rotary movement. The resistance is infinitely adjusted via its position, thereby changing the volume. Dimmers for adjusting the light intensity can also work according to the principle described. The potentiometers available in the eibabo technology store have different designs and can be used in a variety of ways. If you have any questions about products from our range, please feel free to contact us.Catalogue content:In this eibabo® catalogue low-voltage industrial components > potentiometer for control circuit devices you will find items from the following product groups:Item overview:Command deviceControl switchControl unitDialIlluminated pushbuttonIndicator lightIntensity adjusterPotentiometerPotentiometer for command devicesPotentiometer for control circuit devicesPrecision potPrecision potentiometerPush buttonResistanceRotary potentiometerSelector switchSetpoint potentiometerSignaling deviceTurning resistancefrom the following manufacturers:Manufacturer overview catalogue Potentiometer command device:EatonFinderGlen DimplexMegatronMurrelektronikPhoenixRockwellSchneider ElectricSiemensStahlTeleWieland

Lighting control system - By regulating the light intensity, we consciously influence our mood, the way we work or our sleep patterns. An evening for two is much more romantic with dimmed lights, or cooking is much easier if you always have a good view of the pots. Find out here how and with what you can control the brightness in your rooms exactly as you want.The eibabo® technology store offers a very extensive range of items for light control. For example, access our high-quality switches, buttons, potentiometer inserts (generally referred to as dimmers), light sensors, switching modules or components for smart home control. Well-known manufacturers, best quality, fair prices, fast delivery and secure payment are our arguments for shopping in the eibabo® online shop.What are light control systems?Light control systems are traditional or intelligent devices that allow you to control the lighting in a room. Depending on your wishes and needs, there are different types of light control systems available. Probably the simplest example of light control is the classic switch that turns the light on and off. Another option is to switch the light on when movement is detected. A motion detector or a presence detector is used here. But the lighting control can be much more complex and in such cases requires very individual components. And that's exactly what this catalog from the eibabo® online shop is all about.Image: Ledvance DALI PCU lighting control systemWhat types of light control systems are there?In general, there are hardly any limits to the implementation of your lighting control ideas. Depending on your needs, you can simply switch your light on manually, automatically or networked. The more complex the system, the more individual freedom you have to realize your ideas or increase comfort. Even if network systems are more expensive to purchase, they save up to 30% in electricity costs over time thanks to intelligent control management. The following types of light control are possible:Manual light controlManually turning on and off is the most widely used lighting control. It is difficult to save electricity with it. You have to constantly remember to turn on the lights only when you actually need them. The use of economical LEDs can help save on energy costs. Dimming is a slightly more advanced way of controlling room lighting. However, this is also manual. Dimmer switches allow you to dim the lighting to the desired level. This in turn saves a little more electricity.Automatic light controlWith automatic light control, a sensor usually switches the lights on and off. You can specify the criteria according to which this happens and how long such switching cycles last. So you can't forget to turn off the light. To automate outdoor lighting, you may want to install motion sensors. The lighting is then only activated when there is a certain amount of darkness and a person or vehicle is moving in the detection area of the detector. After a certain period of inactivity, the device switches the light off again. Presence detectors or presence sensors are used indoors. Their basic switching principle is comparable to that of motion detectors. These record movements within a room. Presence detectors are ideal for bathrooms, toilets, break rooms and hallways.Networked light controlThe most advanced type of light control is the networked system. This is often part of building automation, but can also be designed as a stand-alone system. Networked lighting systems make it possible to control lighting from computers, multifunction devices, remote controls or smartphones. The prerequisite for this is the connection to a central control unit. Advanced programs can even store data and create usage charts, so you can closely monitor your energy consumption.Basically, we differentiate networked lighting between centralized, wireless or combined light control systems. With the centralized system, all lighting circuits from a room or building come together at a central location. The classic wall switch is replaced by one or more multifunctional pushbutton sensors or touch displays. These allow you to control the light in different ways. This requires an integrated processor that manages the additional functions. Depending on the range of functions of the components and programming, at the touch of a button, for example:call up interesting light scenesdim different lighting groupssynchronize the lighting with the movement of the sunmake switching on and off dependent on the actual brightnessadjust the color of the light sourceGenerate operating hours, consumption and other data through measurement and/or monitoringand so forth An alternative to the centralized solution is the wireless variant. This consists of controllable dimmers and switches that have replaced the traditional standalone switches and dimmers. The wireless system is of particular interest in renovations and retrofits as there are fewer cables to run. The existing installation can usually be built on. The installation is easy, the costs are manageable. The wireless light control can be operated like a centralized system and contain the same programming options. All dimmers and switches are wirelessly connected to the control unit's processor.The advantagesBy adjusting color or intensity, light controls can: Reduce glare; change the atmosphere and mood; make the room function more flexible; reduce energy consumption and increase safety.A combined light control is a mixture of both systems described. Both wireless and wired devices are included in a system and exchange information with each other. This option is often implemented when expanding central systems. All of the systems mentioned offer the user comprehensive and individual comfort and are mostly intuitive and easy to manage.What are the requirements for a networked lighting control system?The individual components of a lighting control system (controllers, ballasts, drivers and light sources) must be compatible with one another to ensure proper operation of the system. This means: The components must communicate in order to be able to execute the control strategy. This so-called interoperability depends on the control method or the protocol. NoticeA protocol is a set of rules that defines the behavior of components in a system in a specific language. Examples of well-known and widespread protocols include the Digital Addressable Lighting Interface (DALI) and ZigBee. All controllers must be designed for the same protocol to ensure good interoperability. The individual protocols differ with regard to the software structure. There are:open or standardized protocols that are available and usable for all manufacturersProtocols that represent an optimized solution for only one manufacturer and bind the user to this manufacturer for future maintenance, changes or extensionsa combination of both; i.e. an open protocol that is tailored to specific providers or a provider-specific protocol that is made available to other providers through licensing If you want to integrate components with different protocols, this is possible by using a gateway (hardware or software). In addition, various applications and software for building automation support the implementation of light control systems. With this you can for example:discover devicesAssign specific control points to lighting zonesProgram scenarios for lighting zonesCalibrate sensors and set actuatorsmonitor checkpointsIssue service warnings and alarmsRecord energy consumption and display, log, evaluate and back up other dataCreate users and access levels Catalogue content:In this eibabo® catalogue Light control > Lighting control system component you will find items from the following product groups:Item overview:Ambient lightCentral controlComfortableControl elementDALI unitHall lightingInterior lightInterior lightsLight control deviceLight line systemLight managementLight meterLightingLighting controlMini sensorMotion detectorMotion sensorMounting frameMounting rail lightRadio linkRain gaugeRotary dimmerSensorsSISignal converterSmartphone controlTwilight sensorUniversal dimmerWarehouse lightingfrom the following manufacturers:Manufacturer overview catalogue Lighting control system:ABBArcliteBarthelmeBEGA GantenbrinkBrumbergBusch JaegerCeagDoepkeEberleEltakoEVNFinderFischerGiraHagerHeraHoubenIDVJungLEDVANCENobileOpple LightingPhilips LichtPräzisaRadiumRegioluxRidi-LeuchtenRZBSchalkSchmitz-LeuchtenSchneider ElectricSignify PLSSitecoSLVThebenTriluxZumtobel

Controller iuminaires - Even before you installed your building's interior and exterior lighting, you thought carefully about the different states you would later like to create using lamps and lights. This can be classic dimming, in which the brightness of connected lamps can be influenced by a potentiometer. This can also be the setting of desired colors if you use the colored LEDs required for this. If you wish, you can control all of this centrally with control units for lights. Depending on the application, such control units are quite different. This can be dimming actuators and controllers with different color channels in the control cabinet, wall panels with touch function for manual control directly as an alternative to the light switch or combination systems consisting of radio remote control and permanently installed receiver. As a large specialist store with a huge range of lights and controls, the eibabo online shop offers you everything you need to implement your individual lighting ideas.Catalogue content:In this eibabo® catalogue Light control > Controller for luminaires you will find items from the following product groups:Item overview:Control unitControl unit for lightsController for luminairesControllersExtensionInterface moduleLED ballastLED controlLED control gearLED controllerLED controllingOperating devicesPlug-in moduleRadio controllerRelay modulefrom the following manufacturers:Manufacturer overview catalogue Controller iuminaires:ArcliteESYLUXEVNScharnberger+Has.Zumtobel

Soft starters - Would you like to avoid suddenly occurring high starting currents when switching on an electric motor, reduce wear and tear on the motor and thus extend its service life? Find out here how a soft starter works and which criteria you can use to select such a device.What is a soft starter?Soft starters, soft starters or soft starters can basically be used in all electric motors. The devices are used in particular for asynchronous motors that are operated with alternating current. The starters work according to the fact that the torque developed by the electric motor is proportional to the square of the starting current and, correspondingly, proportional to the applied voltage. Thus, with a soft starter, by reducing the voltage at the moment the motor starts, you can adjust the torque and current. So, the task of these devices is to keep the motor parameters (current, voltage, torque and so on) within safe limits during the start. This is done to:to relieve the engine drive train when startingto limit the inrush currentto avoid a voltage drop in the mains voltageprevent the miniature circuit breaker in the circuit from responding too quicklyprevent engine overheatingEliminate dropouts and irregularities in the course of the mechanical driveextend engine life What is an asynchronous motor?To understand the importance of soft starters, we need to know something about the motors they are used in. Electric motors run on either direct current or alternating current. When it comes to AC motors, we mainly differentiate between asynchronous motors and synchronous motors. The difference between the two motor variants lies in the detailed design and the interaction between the rotor and stators in the magnetic field generated.Already knew?In a synchronous motor, the rotor speed is always equal to the rotational frequency of the electromagnetic field. In an asynchronous motor, there is a difference between the rotational speeds of the rotor and the rotating magnetic field in the stator.Asynchronous motors of small and medium power are the most commonly used electric motors and are used both in industry and in household appliances. In the industrial environment, three-phase asynchronous motors are used most frequently, for example as drives in construction, in traffic, in public utilities or as drives for water supply devices. The main problems of these engines are:the high starting current, which can be many times higher than the nominal current and thus leads to problems with the performance stabilitythe inevitable difference between engine torque and load torque. When switching on, the torque is often available in fractions of a second. This sudden force can lead to failure of the drive train. A soft starter avoids these problems by slowing the acceleration and deceleration of the motor. As a result, starting currents can be reduced and irregularities in the mechanical part of the drive as well as hydraulic shocks in lines and valves when starting and stopping the motors can be avoided.What is the starting current?The principle of operation of asynchronous motors is based on electromagnetic induction. The build-up of a back EMF from the application of a changing magnetic field during engine start-up causes transients in the electrical system. Definition transientTransients in electric motors are brief voltage peaks caused by switching on the electrical circuit. These transients can affect power supplies and other connected devices. When starting, the engine accelerates to full speed. Meanwhile, the starting current can reach many times the full load current. During this time, the cables must carry more current than when they are running. The voltage drop in the system is also much greater when starting up. This becomes especially clear when starting a powerful power unit or a large number of engines at once.This is why soft starters are increasingly being used when starting high-performance electric drives. The function of the starters is to supply voltage to the motor windings evenly from zero to nominal, which also allows the motor to accelerate smoothly to maximum speed. During the starting process, the soft starter gradually increases the applied voltage and the electric motor accelerates to the nominal speed without high torque peaks and current surges.How a soft starter worksYou have now learned about the main problems involved in starting induction motors. Soft starters counteract these problems and can be either mechanical or electrical or a combination of both. Mechanical soft starters directly counteract the sudden increase in engine speed by limiting the torque, for example, with brake pads, fluid couplings, magnetic locks or counterweights.The electrically constructed devices gradually increase the current or voltage from an initially low level to a maximum voltage. This starts the motor smoothly and gradually accelerates it to its rated speed. These starters usually work with an amplitude control and can therefore also start up when idling or under load. Devices of the newer generation use phase control methods and also start drives with heavy starting.Image: Siemens 3RW4037-1BB04 soft starterWhat types of soft starters are there?Soft starters are phase controlled. Thus, three types of soft starters are used: devices with one, two and with all controlled phases. The first variant is applied to single-phase motors to provide reliable protection against overload and overheating, as well as to reduce the effects of electromagnetic interference. The devices of the second type usually contain a bypass contactor in addition to the semiconductor control board. After the motor has reached rated speed, the bypass contactor is activated and supplies DC voltage to the motor. The three-phase type is the optimal and most technically advanced solution. It provides reliable current and magnetic field strength limitation without phase distortion.What should you consider when buying a soft starter?The main feature of a soft starter is the current rating. This value should be 'many times' greater than the value of the current flowing through the motor winding. How high this 'multiple' is depends on the severity of the launch. When it comes to motors for fans or pumps, the starting current is about three times higher than the rated current. Certain saws or press machines are often devices with heavy starting. These are drives with a large moment of inertia. Their starting current is about five times higher than the rated current. For motors with particularly difficult starting, the starting current can be eight to ten times higher.Please noteA soft start takes time and excess energy is converted into heat. To repeat the starting process, the starters must cool down. Therefore, if your process requires frequent switching on and off, choose a soft starter for heavy or extra heavy starting (even if your machine doesn't actually need it).Decide on a device that controls the required number of phases. In addition, a soft starter works according to a preset program. In other words: The device increases the voltage to the nominal value within a certain time. An integrated control unit with feedback function allows you to control this process and compare voltage and torque or the differences between rotor and stator.If necessary, pay attention to the ability of the starter to work when accelerating or braking. This would require an additional, integrated auxiliary contactor that bridges the main circuit so that it can cool down. This prevents phase asymmetry and overheating of the motor windings. With some models, you can set certain parameters manually using a rotary potentiometer on the device or digitally using a microcontroller. Consider whether you need additional functionality or features. These include:a certain type of protectionthe presence of power saving modesrestart capabilityWorking at reduced speed TIPA properly selected soft starter can double the service life of electric motors and save up to 30 percent electricity. With a soft starter from the eibabo® online shop, you are opting for high-quality goods from well-known manufacturers such as Eaton, Schneider, ABB or Siemens. If you want to control the speed of a machine not only at the beginning, but permanently, then the use of a frequency converter would be an alternative for you.

Front element selector switch - With a selector switch you get the hang of it! Just think of the knob for adjusting the speed of your mixer in the kitchen. The ignition locks in the cars were also typical selector switches, in which the ignition was set individually by turning the key mechanically. But these are slowly disappearing from the vehicles. In any case, depending on the position of the key, one or more circuits could be switched on or off through the various contact arrangements. Selector switches are therefore widespread in professional and private everyday life and can be used to control industrial systems as well as to control small model railways. Whether lockable or with a toggle handle, whether illuminated or with numerous setting positions, your eibabo technology store has different front elements for the selector switch of your project on offer. The rotary switches themselves are also available inexpensively in the eibabo shop.Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Front element for selector switch you will find items from the following product groups:Item overview:ActuatorAgreement switchButtonControl elementEnabling switchFront element for potentiometerFront element for selector buttonFront element for selector switchFront element illuminated selector switchFront element rotary switchFront element selectorGrip buttonHead push buttonIlluminated selection buttonIlluminated selector buttonKey switchPosition guardPulse buttonPush buttonPush button, completeRotary leverRotary switchSelector buttonSelector front elementSwitchToggle buttonToggle switchTurn button (knob)from the following manufacturers:Manufacturer overview catalogue Front element selector switch:ABBCeagEaoEatonEuchnerRockwellSchlegelSchmersalSchneider ElectricSiemensSMC DeutschlandStahl

Display signal lamp - It's hard to believe how often we are all confronted with indicator and signal lamps every day. Most of the time we no longer actively notice them and only notice them when they are defective or missing. Especially in the field of motor vehicle and rail traffic, indicator and signal lamps are ubiquitous and fulfill important tasks. They are of a special design, because in daily use they have to be able to withstand heat and cold as well as withstand vibrations and impacts while maintaining the same light output. Classic signal lamps with incandescent filaments are still installed in many applications. Due to their relatively low power consumption, their consumption often only plays a minor role. Nevertheless, the durable and energy-efficient LED is also finding its way here and enormously complements the product variety. The offer in the eibabo online shop includes both high-quality classic indicator lamps and signal lamps in LED technology.Catalogue content:In this eibabo® catalogue Lamps > Indication- and signalling lamp you will find items from the following product groups:Item overview:Anti-twist protectionBulbsControl unitDouble-coil lampHalogen lampHalogen signal lampHazard warning lampHigh voltage kryptonHigh-voltage standardHigh-voltage traffic signal lampIncandescent lampIndication- and signalling lampIndicator and signal lampLampLow voltage overpressureLow-voltage halogen lampLow-voltage halogen reflector lampLow-voltage overpressure lampLow-voltage traffic signal lampMounting bracketsPear shape lampPotentiometer holderRing mirror lampSelector switchSignallerThreaded ringTraffic signal lampTraffic signalling lampfrom the following manufacturers:Manufacturer overview catalogue Display signal lamp:ABBBosch Power ToolsBusch JaegerCeagEatonGrotheHellumJungKonstsmideLegrand BticinoLegrand SEKOMakitaNovarPhoenixRafiRenzRockwellScharnberger+Has.Schneider ElectricSiemensSirenaSommerWerma
