New 65W Compact Medical Grade Power Adapters are Low Cost and Approved to the Latest Safety Standards

Press release date: Feb 01, 2014

Santa Clara, California, USA — TRUMPower launches the TMP65 series of low cost medical grade AC/DC desktop power adapters, which has both Class I and Class II models availability.

The TMP65 Class II units, furnished with an IEC 320/C8 AC inlet without a ground pin, are double insulated to provide proper safety protection where the availability and integrity of an earth cannot be guaranteed. Class I units come with an IEC 320/C6 AC inlet that has a ground pin. Both Class I and Class II units come with a 5.5 x 2.5 x 11 mm right angle barrel plug as the standard output connector. The series offers standard single output voltages of 12V, 15V, 18V, 19V, 20V or 24V with continuous output power of up to 65 watts; non-standard output voltages are available upon request. TRUMPower offers many additional connector options and can accommodate special requirements as well.

The TMP65 series is approved by UL and TUV to the latest 3rd edition medical standards, including IEC/EN 60601-1:2008, ANSI/AAMI ES 60601-1: 2005 and CSA-C22.2 No. 60601-1:08. The power adapter complies with EN 60601-1-2 EMI and immunity standards including EN 55011/FCC/VCCI class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-3-3, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, EN 61000-4-11.

With efficiency higher than 87%, the TMP65 series is in compliance with CEC and Energy Star efficiency level V requirements. It also carries CE marking and is RoHS compliant as well. No minimum load is required while still maintaining 5% tolerance throughout the full load range. Packaged in a low profile black-colored plastic enclosure, the unit has a compact size of 5.08 x 2.01 x 1.22 inches. White-colored units are available upon request.

The power adapter has an 85 to 265 VAC continuous input range with 0.98 active power factor. Class I units can withstand 5,600 VDC from input to output, 2,100 VDC from input to ground, 700 VDC from output to ground and Class II units have a withstand voltage of 4000 VAC from input to output. With touch current being lower than 100µA, the TMP65 power adapter has a low earth leakage current of 300µA maximum at 264 VAC/63 Hz and can operate at an ambient temperature range of 0°C to +60°C, with no derating required between 0°C to +40°C. The MTBF is higher than 150,000 hours at full load and 25°C ambient per MIL-HDBK-217F. The power supply is fully protected against overvoltage, overload, and short-circuit conditions.

With lead-times from stock to 8 weeks, the TMP65 series is economically priced at $18/ea in OEM quantities.
