40/65W PSUs meet 3rd edition medical safety standard

August 22, 2013 // By Graham Prophet
Murata's MVAD040 and MVAD065 open frame, convection cooled AC-DC power supplies come in a standard 2 x 4 in. format with a low profile, 1U-compatible 1.3 in. height (50.8 x 101.6 x 33.02 mm), and are suitable for use in medical and healthcare appliances, data storage and networking, and industrial factory automation systems.

Up to 90% efficient, the MVAD040 and MVAD065 do not require additional heatsinking or forced air cooling to operate at full output power. No load power consumption is less than 0.3W, which meets ErP and Energy Star requirements. Accepting the universal input voltage range from 90 to 264 VAC, each model is available with a +12, +24, or +48 VDC output. Operating temperature startup is as low as – 20C. MVAD065 features remote sense, which compensates for lead losses up to 0.4 VDC at the load point.

The supplies comply with the stringent demands of the internationally recognised 3rd edition medical safety standard IEC/EN 60601-1: 2006. They also meet the IEC/EN60950-1 safety standard for IT equipment. The MVAD series has an MTBF of one million hours.
