ICL-28R/L Series 28A AC Inrush Current Limiter
By: Frank Chen/ Product Manager
Since MEAN WELL released the first AC inrush current limiter in April 2019, the ICL-16R/L (16A) helped solve headaches of many end system designers regarding AC breakers. When the AC power system powers on a capacitive or inductive load, such as switching power supply, there is a temporary inrush current peak, which may cause AC circuit breakers to trip even though the continuous current draw is well below the breaker ratings. End system designers often have to oversize the breaker or separate load on multiple AC circuit breakers to ensure the system stability. The MEAN WELL ICL can be added after an AC circuit breaker to suppress the inrush current draw, which can help prevent AC circuit breakers from falsefully tripping, and it can help reduce the installation cost of the end system.
As a response to high demands from the market for higher current inrush current limiters, MEAN WELL quickly releases the ICL-28R/L series that can support higher current ratings than the ICL-16R/L, allowing more power supplies and larger capacitive loads to be installed on a single circuit breaker. Additionally, in order to satisfy installation requirements of different applications, MEAN WELL is releasing DIN rail type ICL-28R and linear type ICL-28L for customer selection.
