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 0.5 W 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 228 µA 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 to +40°C. The units deliver a reliable 140K hours-minimum MTBF at full load at 25°C ambient per MIL-HDBK-217F.

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.
