160W Medical Grade Adapter Meets 4th Edition EMC Standards

October 02, 2017 by Paul Shepard

TRUMPower has released the new 160W TDM160 series of low cost medical grade ac-dc desktop power adapters to its product line-up. Using the power supply ensures compliance to the latest IEC/EN 60601-1-2 4th edition medical EMC standards.

The TDM160 Class I units are furnished with an IEC 320/C14 or IEC 320/C6 ac inlet. The power adapters are available with 12V, 19V, 24V or 48V outputs, making them suitable for a wide range of applications. Standard output plug is a 4 pin DIN. TRUMPower offers additional connector and cable options upon request.

The TDM160 series is approved by UL/cUL and TUV to the latest medical standards, including IEC/EN/UL 60601-1 Edition 3.1, ANSI/AAMI ES 60601-1: 2012, CSA-C22.2 No. 60601-1: 2014.

The power adapter complies with IEC/EN 60601-1-2 4th edition medical EMC and immunity standards including EN 55011/FCC/CISPR 11 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 61000-4-8, EN 61000-4-11.

With efficiency of 88% minimum @ full load, the TDM160 series satisfies CEC & DOE level VI and ErP stage II requirements. It carries CE marking, is RoHS compliant and has PSE approval as well. Packaged in a low profile black-colored plastic enclosure with LED power indicator, the unit has a size of 7.2 x 3.18 x 1.65 inches.

The 2 MOPP rated power adapter accepts a 90- to 240-Vac continuous input range and 0.95 power factor. Withstand voltage is specified at 4,000Vac from input-to-output (2 x MOPP) and 1,500Vac from input-to-ground (1 x MOPP). Earth leakage current is lower than 300µA @ 264Vac.

The TDM160 power adapter can operate at an ambient temperature range of 0°C to +40°C and operating humidity spans from 20%-80% non-condensing. Its MTBF is higher than 300,000 hours at full load and 25°C ambient, calculated per Telecordia SR-332.

With no load power consumption <0.15W, the power supply is fully protected against over voltage, over temperature, over current, and short circuit conditions.
