The RAC03-SC series is an ultra-compact universal input AC/DC power
module for PCB mounting. It features high efficiency, low standby power,
high operating temperature, soft start, low output ripple/noise, overload
and short-circuit protection as well as a built-in EMC Class B filter. Output
voltages range from 3.3VDC to 24VDC, including a 3.8VDC version
designed for battery chargers and GSM modems.
