Inrush Current Limiters
The inrush current indicates the maximum input current drawn when a load is switched on. Since this current is usually higher than the rated current (e.g., due to the initial charging of installed capacitors), circuit breakers can be accidentally triggered without appropriate countermeasures. This reduces the reliability of the entire electrical circuit. Inrush current limiters prevent this. For LED power supplies, a so-called inrush current limiter (transformer switching relay) is suitable, which is connected between the circuit breaker and the LED power supply(s). In addition to preventing unwanted interruptions, the installation of an ICL also enables the operation of a larger number of LED power supplies on existing circuit breakers. This results in immediate savings. In addition to its own brand PICL, ProConnecting offers inrush current limiters from the renowned manufacturer Mean Well. The inrush current limiters are available in both DIN rail (TS-35/7.5 and TS-35/15) and linear designs. PICL and MeanWell inrush current limiters are available for a rated current of 16A and 28A.
