AC/DC power supplies from Gresham meet medical needs

Gresham Power Electronics has introduced two series of universal input AC/DC power supplies from Polytron Devices for use in medical applications. The MUI65 dual and triple output and MUI40 single output devices are claimed to have a market-leading, low standby power consumption of just 0.15W, together with an 85 to 264V AC, 47 to 63Hz input range and low leakage current under 75-microA.

The MUI65 is particularly suitable for use in applications up to 65W, says Gresham. It offers low cross regulation under 1.5 per cent and is delivered in a 2.0 x 3.5-inch (50 x 89mm) package. The MUI40, available in a 2.0 x 3.0-inch (50 x 76mm) package, is intended for applications up to 40W.

Additionally, both devices feature a built-in class B EMI filter, 2MOPP (means of patient protection) insulation and 5000M operating altitude. The MU165 and MU140 are RoHS-compliant and meet medical electrical safety standards including ANSI/AAMI ES60601-1, EN6060-1 and IEC60601-1 3rd edition.

Jake Moir, managing director, Gresham Power, says: “The market for medical electronics continues to grow and we are pleased to be able to add these two new power supplies from the long established Polytron Devices to our product range. The on-board level B EMI filter will be an advantage to system designers who will no longer have to provide additional external filtering reducing their costs and PCB space required.”
