TRUMPower is proud to announce their newest addition to
their line of medical power supplies with the TMA250 series of 250W AC/DC power
adapters. The TMA250 series provides DC output voltages ranging from 12V to
The TMA250 series features a 90 to 264 VAC universal input
and 0.9 active power factor. With efficiency being 87% minimum and no-load
power consumption 0.5W maximum, the power adapters meet CEC and Energy Star
Level V standards. The units come with a standard IEC320/C14 AC inlet and a
Molex Mini-Fit 6-pin or APP PP45-1345 DC output connector while withstanding
5,656 VDC from input to output and 2,121 VDC from input to ground. The power
adapters feature a low leakage current of 228µA at 264 VAC.
Other key features of the TMA250 series include overvoltage,
overload, and short-circuit protections. Equipped with a thermally-controlled
cooling fan, the models can be fully loaded at -20°C to +40°C. The units
deliver a reliable 140K hours-minimum MTBF at full load at 25°C ambient per
The TMA250 models comply with RoHS requirements and EMC
standards that include EN60601-1-2, EN55011 & FCC part 18 Class B.
Additionally, the power adapters are UL, TUV, CB, CE approved to UL 60601-1, EN
60601-1, IEC 60601-1, and CSA C22.2 No. 601.1 medical standards.
