RPA20-2405SAW/N-HC

The RPA20-2405SAW/N-HC from Recom Power is a RPA20-AW series 20W single output DC to DC converter with negative control function and glued heatsink. This high power density converter has 4:1 wide input voltage range and industry standard 1”x1” case size. Despite its small size, the RPA20-AW converter is fully specified device with high efficiency, no minimum load, 1600VDC isolation, tight regulation and low ripple/noise figures. This single output DC to DC converter offers a ±10% trim range. The outputs are also fully protected against overtemperature, short circuits, overcurrent and overvoltage. The converter finds many uses in railway applications where board space is at a premium. It has Pi-type internal input filter.
