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.

Notes:
Note1: Measured @ 230VAC / 50Hz / Ta=25°C with constant resistant mode at full load.
Note2: If used @ 115VAC / 60Hz with full load, max. capacitive load is less, please contace RECOM for detailed information.
Note3: Start up only is guaranteed at temperatures down to -25°C. Other specifications may not be met.
