TDK-Lambda WMM30 Wall-Mount Medical Power Supplies

TDK-Lambda WMM30 Wall-Mount Medical Power Supplies offer 25W to 30W rating with output voltages of 5V, 9V, 12V, 15V, 18V, or 24V. The WMM30 power supplies have a wide 80VAC to 264VAC input, input-to-output isolation of 4kV (2 x MOPP), and a leakage current of less than 50µA. The units have four interchangeable AC input plugs suitable for Europe, North America, the UK, and Australia, which are sold separately. The output cable is terminated with a straight 5.5mm x 2.1mm x 12mm (OD x ID x L) connector, with other types of connectors and cable assemblies available on request.

To meet the EU and US efficiency standards, the series has an average efficiency level of >85% to >87.7% (model dependent) and an off-load power consumption of <75mW. The rugged plastic enclosure is vent-free (IP22) and measures 96.7mm x 58mm x 43.25mm (LxWxD). The WMM30 operates in ambient temperatures of -25°C to +70°C, derating linearly to 50% load from +40°C to +70°C. The TDK-Lambda WMM30 Wall-Mount Medical Power Supplies are suited for home healthcare, hospital, clinical, dental, and life sciences applications for monitoring, imaging, and diagnostic equipment.

Certified to the medical safety standards IEC 60601-1 and EN 60601-1-11 and compliant to EN 60601-1-2 Edition 4 for EMC, the products have a Class II input requiring no earth ground. The WWM30 also meets the EU Tier 2 [(EU) 2019/1782] and DoE Level VI efficiency standards. The WMM30 is certified to IEC/ES/EN 60601-1, meets IEC 60335-1 (Household Appliances), and carries the CE mark for the low voltage, EMC, and RoHS directives. The series complies with the EN 55011 (Class B) and EN 60601-1-2 Ed4 EMC standards.
