TRUMPower has released the new 120W TDM120 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 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 12V, 15V, 18V, 19V, 20V, 24V 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 18V-48V models are equipped with a 2.5 x 5.5 x 9.5mm 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 at 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 plastic enclosure with LED power indicator, the unit has a size of 6.62 x 2.60 x 1.54 inches.
The 2 MOPP rated power adapter accepts a 100- 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). With earth leakage current being lower than 300µA at 264Vac, the TDM120 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.
