-December 02, 2017

VMS series open-frame AC/DC power supplies from CUI are certified to medical 60601-1 edition 3.1 safety standards for 2X MOPP applications and 4th edition EMC requirements. The VMS-180, VMS-225, VMS-275, VMS-350, and VMS-550 series deliver 180 W, 225 W, 275 W, 350 W, and 550 W, respectively.

Units are housed in 2×4-in. and 3×5-in. packages with profiles as low as 0.75 in. They achieve high efficiency of up to 94% and power densities of up to 30 W/in.3 Each series offers output voltage options ranging from 12 VDC to 58 VDC and a wide universal input voltage range of 80 VAC to 264 VAC.

The VMS power supplies limit no-load power consumption to 0.5 W. All of the devices provide input-to-output isolation of 4200 VAC, with leakage current as low as 0.3 mA at 230 VAC. At full load, the supplies operate over a temperature range of -40°C to +50°C, derating to 50% load at +70°C.

Suitable for medical, dental, and home healthcare equipment, the VMS power supplies meet EN55011 Class B limits for conducted and radiated emissions and attain an MTBF of 3.37 million hours, calculated per Telcordia SF-332 Issue 3. Other features include power factor correction; a 12 VDC, 500 mA fan output; and overvoltage, overcurrent, and short-circuit protection.

Prices for the VMS power supplies start at $108.94 each in lots of 25 units. Delivery is from stock to 12 weeks.
