Adding the new 25-36W TDM36 series of low cost medical grade AC/DC desktop power adapters, TRUMPower has expanded 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 5, 7.5, 9, 12, 15, 18 or 24V with continuous output power of up to 36W; other output voltages are available upon request.
Both Class I and Class II units come with a standard 2.5x5.5x9.5mm 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-coloured plastic enclosure with LED power indicator, the unit has a compact size of 3.94x1.97x1.3”.
The BF rated power adapter has a 90-264VAC continuous input range and 0.9 power factor. Withstand voltage is specified at 4,000VAC from input to output (2xMOPP) and 1,500VAC from input to ground (1xMOPP).
With touch current being lower than 100µA, the TDM36 power adapter can operate at an ambient temperature range of 0-40°C. It’s MTBF is higher than 300,000 hours at full load and 25°C ambient, calculated per Telecordia SR-332. With no load power consumption <0.1W, the power supply is fully protected against overvoltage, over-current, and short circuit conditions.
