FPM110 - 72~110 Watt Medical Triple Output Power Supplies, 72~110 Watt Medical Triple Output Power Supplies : FPM110

Medical Open Frame

The FPM110 series of compact, open PCB constructed, AC-DC switching power supplies are specially designed for medical applications. They are capable of delivering 72-110 watts of continuous power at 25 CFM forced air cooling or 60-80 watts at convection cooling. They operate at 85-264 VAC input voltage without the need of a selector strap. All models meet the safety requirements of UL, CSA for medical equipment. FPM110-zyyy x = S, D, T or Q to denote multiple output ; S for single output, D for dual output, T for triple output, Q for Quad output, yyy to denote different output rating.
