Description
Specifications (measured at TA = 25°C, nominal input voltage, full load and after warm-up)
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. Re-
mote 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 out-
puts with 3A load current have raised output voltages to compensate for track losses as stan-
dard.
Input Voltage Range 2:1 or 4:1
