PFMUIU500 Medical Power Supplies

PFMUIU500 Series 500-watt switching power supplies feature an ultra-small 5.5 by 3.25 by 1.6-inch U-frame design for space-constrained medical applications. The units accept inputs of 90 to 264V AC and 127 to 370V DC, and they deliver 500 watts of output power with a 30-CFM fan and 200 watts with free air convection. Providing 4,000V AC input to output 2xMOPP insulation for patient safety, these medical power supplies meet the UL/IEC/EN 60601-1 edition 3.1 safety standard, and they offer high efficiency to 93 percent, standby of 5V at 1A with fan and 0.4A without fan, remote ON/OFF, a PFC function of >0.94 and optional current share function on most models. PFMUIU500 power supplies also come with a 12-V, 0.3-A auxiliary output.
