Description
The RAC03 series is an ultra-compact low cost universal input AC/DC power module
for PCB mounting via slots in the PCB (pinless connectors).
It features ultralow no-load power consumption, short circuit, overload and output
overvoltage protection as well as a built-in EMC Class B filter.
