Medically Approved 400W ATX PC Power Supply Unveiled by TRUMPower

With its 90-265 VAC universal input and active PFC, the power supply can be used globally without changing input settings.

The TMPC-400 is approved to UL 60601-1, IEC 60601-1, and EN 60601-1 medical standards and complies with EN 60601-1-2 EMC standards, including EN 55011, EN 61000-3-2, EN 61000-4-2, EN 61000-4-11. It has an MTBF > 200,000 hours @ 25°C. Along with the typical earth leakage current of 90µA @ 115 VAC or 150µA @ 230 VAC, there is a version with a low leakage of < 90µA @ 264 VAC available.

The unit complies with ATX12V and EPS12V standards. It consists of DC voltage outputs and maximum loads of +3.3V/30A, +5V/30A, dual +12V/17A, -12V/0.8A, +5Vsb/2A, -5V/0.3A respectively. The maximum overall output is 400W, with +3.3V/+5V/+12V providing a maximum power of 380W and the combined output of +3.3V and +5V limited to 180W. The power supply includes a standard output cableset that can meet the requirements of most applications. But any other special requirements of the cableset can be accommodated as well.

The TMPC-400 contains a thermally controlled ball-bearing fan with noise-killer as well as a power switch. Additional features include short circuit protection on all outputs, output overvoltage protection, resettable power shutdown, low ripple and noise, and 0ºC to 50ºC operating temperature.

The TMPC-400 is priced at $249 in OEM quantity. Units are available from stock to 8 weeks ARO.
