USB Power Meets 4th Edition Medical EMC

TRUMPower releases its new 5V/2A TMW10 USB series of medical wall mount adapters which are available in black or white color, with a USB socket on the case or a molded output cable with a dc plug. The switching power adapters feature 90- to 264-Vac, 47- to 63-Hz universal input in fixed or interchangeable ac plug configurations. There are 4 different types of AC wall plugs to meet worldwide requirements: US, EU, UK, and Australian. The units have touch current of 100µA maximum.

The 5V output power supply delivers 10W of continuous output power and comes with the built-in USB type A receptacle on the case as its standard. TRUMPower offers other connector options such as Mini USB type A and B, Micro USB type A and B, or barrel connectors and can also accommodate special requests.

The wall mount adapters are protected against over-voltage, over-current, and short-circuit conditions. The units can withstand 4,000Vac from input-to-output. They have a minimum efficiency of 78% at full load and can operate at an ambient temperature range of 0 to +40 degrees C. MTBF is 300k hours minimum at full load, 25 degrees C ambient, calculated per Telecordia SR-332

The TMW10 series is certified by UL/cUL, CB, TUV/GS to the latest medical standards, including UL/IEC/EN 60601-1 (Edition 3.1), IEC 62366:2007+A1, EN 62366:2008+A1, ANSI/AAMI ES 60601-1 (2012), CSA C22.2 No. 60601-1 (2014) and by CB to IEC/EN 60950-1 2nd edition ITE standards. It also has PSE (J60950-1 and J55022) approvals.

The power adapter meets IEC/EN 60601-1-2 4th edition medical EMC and immunity standards including EN 55011, CISPR 11, FCC class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-3-3, EN 61000-4-2 (ESD at 15kV air and 8kV contact), EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, EN 61000-4-11. The units are DOE/GEMS level VI and ErP stage II compliant.
