Description
20 Watt
The REC20-xxxxS_D-series offer single and dual regulated outputs in a 2”x1” 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.
