Tumbler Technologies 60W Medical Power Adapters Comply With CEC & Energy Star Requirements

January 04, 2009 by Jeff Shepard

Tumbler Technologies + TRUMPower launched the TMP60 series of medical grade ac-dc desktop power adapters, which deliver up to 60W of output power.

Meeting CEC and Energy Star level IV requirements, the TMP60 power supplies (single ouput models) have an average efficiency ≥85% and standby power consumption less than 0.5W. Earth leakage current on the TMP60 power adapters is 90 µA @ 115Vac/60Hz or 150 µA @ 230Vac/50 Hz typically. The units also meet RoHS requirements. The TMP60 series is approved to EN 60601-1, UL 60601-1, and CSA C22.2 No. 601.1 medical standards and complies with EN60601-1-2 EMC standards including EN55011/FCC/VCCI class B (conducted and radiated emissions), EN61000-3-2, EN61000-4-2, EN61000-4-3, EN61000-4-5, EN61000-4-11, and more.

The TMP60 series includes single, dual and triple outputs. On single output models, the output can be preset at anywhere between 11-39V or 46-50V during production. Dual and triple output models offer combinations of +3.3V, +5V, ±12V, ±15V, and +24V outputs. Enclosed in a 94V-1 rated polyphenylene-oxide case with dimensions of 2.95 x 5.79 x 1.65 inches, the units come with a 5-pin DIN plug as the standard output connector and an optional power switch.

With its 85 to 264Vac wide input and a built-in IEC 320/C14 ac inlet mating with different types of ac power cords, the power adapters can be used world-wide. The series has overvoltage protection that is set at 112-140% of its nominal output voltage and provided on output 1 only.

Overcurrent protection is supplied on all outputs protected to short circuit conditions. The power supplies also contain a LED indicator. The units operate between 0 and +60°C, with derating required starting at +40°C. The withstand voltage is 4000Vac from input to output, 1500Vac from input to ground, 500Vac from output to ground. The series has a calculated MTBF of 150,000 hours minimum at full load at 25°C ambient per MIL-HDBK-217F.

The TMP60-1X series is priced at $45.50 in OEM quantity. Units are available from stock to 6 weeks ARO.
