DC/DC Converter
REC15-S_D(Z)/M
15 Watt
2“ x 1“
Metal Case
Single and Dual
The REC15-xxxxS_D/M -series offer single and dual regulated outputs in a 2”x1” package with 2kVDC
or 3kVDC isolation options and are suitable for higher power industrial applications. Remote on/off
control is standard. The converters can deliver 150% rated power for short periods of time to cope with
applications with large capacitive loads or high start up currents. The outputs with 3A load current have
raised output voltages to compensate for track losses as standard.
