The power supplies with an AC input of 90…264 VAC with active power factor correction (PFC meet EN 61000-3-2)) have an efficiency of up to 94% and operate within a temperature range of -40 up to 80°C (>+40 °C with derating) without active cooling.
The series is designed for PCB mounting; a covered version is also available. The devices are overvoltage, overtemperature, overcurrent as well as short-circuit protected. CFM300M series also offers a very low no load power consumption (<0.3 W) and extremely low leakage current (300 µA).
