36W Medical Grade Adapter Meets IEC/EN EMC Standards

TRUMPower has added the new 25- to 36-W TDM36 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 EMC standards.

The TDM36 Class I units come with an IEC 320/C6 or ITE 320/C14 AC inlet and class II units are furnished with an IEC 320/C8 or IEC 320/C18 AC inlet. The series offers standard single output voltages of 5V, 7.5V, 9V, 12V, 15V, 18V or 24V with continuous output power of up to 36 Watts; other output voltages are available upon request. Both Class I and Class II units come with a standard 2.5 x 5.5 x 9.5 mm barrel output connector. TRUMPower offers additional connector and cable options and can accommodate special requirements.

The TDM36 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 & 55022/FCC/VCCI 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 84% minimum at full load, the TDM36 series is in compliance with CEC and Energy Star 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 compact size of 3.94 x 1.97 x 1.3 inches.

The BF rated power adapter has a 90- to 264-Vac continuous input range and 0.9 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). With touch current being lower than 100µA, the TDM36 power adapter can operate at an ambient temperature range of 0 to +40 degrees C. Its MTBF is higher than 300,000 hours at full load and 25 degrees C ambient, calculated per Telecordia SR-332. With no load power consumption <0.1W, the power supply is fully protected against overvoltage, over-current, and short circuit conditions.
