The REC30-xxxxS_D -series offer single and dual regulated outputs in a 2”x1.6” package with 1.6kVDC
isolation and are suitable for higher power industrial applications.
Remote on/off control is standard.
The higher current outputs have raised output voltages to compensate for track losses as standard. The
converter is fully certified to UL/EN/IEC safety standards.
