Low cost 120W medical grade desktop adapter

The new 120W TDM120 series of low cost medical grade AC/DC desktop power adapters has been added to TRUMPower’s product line-up. Using the power supply ensures compliance to the latest IEC/EN 60601-1-2 4th edition medical EMC standards. The TDM120 Class I units come with an IEC 320/C14 or IEC 320/C6 AC inlet and class II units are furnished with an IEC 320/C18 or IEC 320/C8 AC inlet.

The power adapters are available with 12, 15, 18, 19, 20, 24 or 48V outputs, making them suitable for a wide range of applications. Standard output plug for the 12V and 15V models is a 4 pin DIN.

The 18-48V models are equipped with a 2.5x5.5x9.5mm barrel connector as the standard. TRUMPower offers additional connector and cable options upon request.

The TDM120 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 87% minimum @ full load, the TDM120 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 6.62x2.60x1.54”.

The2 MOPP ratedpower adapter accepts a 100-240VAC continuous input range and 0.95 power factor. Withstand voltage is specified at 4,000VAC from input to output (2 x MOPP).

With earth leakage current being lower than 300µA @ 264 VAC, the TDM120 power adapter can operate at an ambient temperature range of 0 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.
