FDM400 - 400 WATT DESKTOP TYPE MEDICAL POWER SUPPLIES

Medical DeskTop Adapter

The FDM400 series of AC-DC switching power supplies are for 400 watts of continuous output power. They are enclosed in a 94V-0 rated polycarbonate case with an IEC 320/C14 inlet to mate with interchangeable cord for world-wide use. All models meet EN55011 class B emission limits, and are designed for medical applications.
