The WMM30 series of medical wall mount power supplies are rated from 25 to 30W with output voltages from 5V to 24V. Certified to the medical safety standards IEC/ES/EN 60601-1 and EN 60601-1-11, they are compliant to EN 60601-1-2  for EMC and designed to meet IEC 60335-1 (Household Appliances). The units are fully-isolated for use with B and BF rated equipment, having an input to output isolation of 4,000Vac (2 x MOPP) and leakage current less than 50µA. Requiring no earth ground, the Class II power supplies are suitable for home healthcare, hospital, clinical, dental and life sciences applications for monitoring, imaging and diagnostic equipment.

With off-load power draw as low as 75mW and high average efficiencies, the units are compliant to ErP Directives and the DoE VI standards. Four interchangeable AC plugs are available (sold separately) for use in Europe, North America, the UK and Australia. The output cable is terminated with a straight 5.5 x 2.1 x 12mm (OD x ID x L) connector, with other types of connectors and cable assemblies available on request.

Housed in a rugged plastic case, which is vent-free and IP22-rated, the WMM30 units measure 96.7mm in length, 58mm in width and 43.25mm in depth. They operate in ambient temperatures of -25 to 70°C, derating linearly to 50% load from 40 to 70°C. All models carry the CE mark for the Low Voltage, EMC and RoHS Directives. The input to output isolation is 4,000Vac (2 x MOPP) and the leakage current less than 50µA.
