Medical grade power adapters approved for use in home healthcare

TRUMPower introduces the TXM25 series of 25W wall mount power adapters that meet 2 MOPP, are approved to Class II medical standards and also comply with IEC 60601-1-11:2015 for home healthcare environment use.


The series accepts a 80-275VAC full range AC input and features short circuit and overload protections. The output voltage is factory preset between 3 to 55V to meet customer’s requirements. The standard output connector is a barrel plug on a 4 feet output cable but to accommodate specific needs, many other desired connector options can be used as well. The customer has a choice of four types of interchangeable plugs, including US, China, Japan, EU, UK, and Australian, which come with the adapter main body. The adapter measures approximately 2.95×1.71×1.58″.

The enclosure leakage current is 100µA maximum @ 240VAC, 60Hz on this double insulated Class II power adapter series. Operating altitude is 3,000m maximum. Other important features are its approvals to UL/IEC/EN 60601-1 edition 3.1, ANSI/AAMI ES 60601-1 (2012), CSA C22.2 No.60601-1 (2014) as well as its compliance with RoHS2, CEC. The power adapter complies with IEC/EN 60601-1-2 4th edition medical EMC and immunity standards including EN 55011 & CISPR11/FCC & VCCI class B (conducted and radiated emissions), EN 61000-3-3, EN 61000-4-2 (ESD at 15kV air and 8kV contact), EN 61000-4-3, EN 61000-4-8, EN 61000-4-11.

The series is rated for operating at -10 to +70°C ambient temperature, with de-rating required from 100% at +40°C linearly to 50% at +70°C. The units consume very low no load power, typically less than 0.3W and have an efficiency of 65 to 86% minimum. The MTBF is 100,000 hours at full load at 25°C ambient temperature per MIL-HDBK-217F standards.

The TXM25 is competitively priced in OEM quantity. Units are available from stock to 8 weeks ARO.
