Can you connect 2 LED Limiters to a group?
Yes, on a 16A group one may place 2 LED Limiters which can both be loaded to 8A.
- › Can you connect 2 LED Limiters to a group?
- Has the application of circuit breakers affected the installation?
The cable length in the installation affects safe shut-down. As the response value increases, the cable length becomes shorter. (Section 41 NEN1010)
- What can you do to combat inrush current?
Regulating the inrush current prevents an inrush surge. You can do that with an LED Limiter (current-limiting resistor)
- Is fluorescent lighting also subject to inrush current?
Yes, due to the coils, a surge of about 5x Inom. occurs.
- What inrush current is an LED fixture subject to?
The inrush current surge is usually described in the technical documentation. In some cases, this can be as high as 100 x Inom.
- Can I replace fluorescent lighting 1-to-1 for LED lighting?
One light will not be a problem. But if there are many, there will be a huge inrush current. You can avoid this by fitting an LED Limiter.
- How many LED bulbs can go on 1 group?
Without measures, only a few fixtures can go on 1 group. If the fixtures are switched on at the same time, you can calculate how many there should be. Often the supplier specifies how many can be switched on at once.
- Can a motion sensor switch LED lights?
Here’s a closer look at what the maximum current of the switch should be. This is between 4 and 10 Amps. If larger current surges are regularly switched, the contacts will burn.
- Is it possible to put an LED Limiter in any circuit?
As long as the technical details are followed, it can be done.
- Is an LED Limiter only for new installations?
A LED Limiter also be retrofitted in old installations. If it is a pluggable installation it is actually very easy
- Is LED lighting mandatory?
Yes, the government has specified for buildings that, in terms of sustainability, LED lighting should be used.
- Where can I fit the LED Limiter?
Wherever multiple LED fixtures need to be switched simultaneously.
- Is the LED Limiter pluggable?
The LED Limiter features Wieland GST18i3® connectors with black coding.
- How high is the inrush current of an LED lamp?
The inrush current surge is usually described in the technical documentation. In some cases, this can be as high as 100 x Inom.
- How many LED fixtures can be connected to the LED Limiter?
The LED Limiter can be loaded up to 8A. So the total rated current of all fixtures connected to it may be 8A combined.
- How heavily can the LED Limiter be loaded?
The LED Limiter can be loaded up to 8A. So the total rated current of all fixtures connected to it may be 8A combined.
- Can you connect multiple LED Limiters to a group?
Yes, multiple LED Limiters may be connected to a group. As long as the maximum current of the group is not exceeded.
- How high is the inrush current when using an LED Limiter?
The LED Limiter eliminates the inrush current surge of the LED fixtures connected to it. So there is no more inrush current surge (at power-on). The current remains at its nominal value.
- What is the part number of the LED Limiter?
- What is inrush current?
- What devices cause inrush current?
LED drivers, among others. All devices with capacitors or coils in the supply section.
- What causes inrush current?
Capacitors are included in LED driver circuits. When the voltage is switched on, the resistance is close to 0 ohms for a short time. This means the current is almost infinite. After a few milliseconds, this effect disappears.
- How does inrush current affect switches and relays?
The enormously high current surge can cause contacts to burn-in. After a longer time, a resistance develops across the contact which causes heat generation.
- How does inrush current affect screw-type fuses?
A fuse is a slow protection device but will melt through at a certain value. The higher the surge the faster the fuse melts.
- What impact does inrush current have on circuit breakers?
A circuit breaker will switch off at a certain current surge. The higher the surge the faster the breaker shuts down.
- What maximum inrush is permissible for switches?
Many switching elements are capable of switching 10A. This is stated in the technical description.
- What maximum inrush is permissible for fuses?
Depending on the type of fuse, a different surge is permissible. For detailed information, see the technical information of the fuse.
- What maximum inrush is permissible for circuit breakers?
Depending on the type of circuit breaker, it will trip at a surge of B-5, C-10 or D-20 times that circuit breaker’s rated current.
- What circuit breakers can be used?
Normally, B-breakers are used. In exceptional cases C-breakers. In industrial applications, D-breakers are used. Please note that replacing a B circuit breaker with a C circuit breaker halves the maximum permissible length of the installation, as the minimum short-circuit current (10xIn) doubles.
