Medically Approved 350 W Power Supply for 1 U InstallationTumbler Technologies + TRUMPower launches the 350W TMPC-350-1U, which has a height of 1.59 inches that makes the medical grade PC power supply suitable for 1U and other applications where height is limited.

With a wide 90-264 universal input and active PFC that complies with EN61000-3-2 standards, the TMPC-350-1U is UL, cUL, VDE, CE approved to UL 60601-1, EN 60601-1, and IEC 60601-1 3rd edition medical standards. The power supply complies with EN60601-1-2 EMC and immunity standards, including EN55011, FCC and VCCI class B conducted and radiated emissions, EN61000-3-2, EN61000-4-2, EN61000-4-3, EN61000-4-5, and EN61000-4-11. The unit is CE marked and RoHS compliant and meets ATX12V and EPS 1U 2.0 standards as well. It has a MTBF > 100,000 hours @ full load, 25°C ambient, calculated per MIL-HDBK-217F and earth leakage current of 220µA @264 VAC, typically.

The TMPC-350-1U has DC output voltages and maximum loads of +3.3V/16A, +5V/18A, +12V1/16A, +12V2/16A, -12V/0.5A, -5V/0.2A, +5Vsb/2.5A. Maximum overall output is 350W, with 331W maximum combined output on +12V1, +12V2, +5V, +3.3V and total output on +3.3V, +5V limited to 130W. The power supply comes with a standard output cableset, which includes the 20+4 pin ATX motherboard connector, 4-pin Molex, SATA power connectors, etc that is suited for most PC-related applications. But any alternative requirements of the cableset can be requested as well.

With efficiency being 80% minimum at full load, the TMPC-350-1U operates at 0°C to 50°C. The unit measures 3.94” x 1.59” x 7.48” and comes with an IEC 320/C14 AC inlet, on/off switch, and durable ball-bearing fans. It features input line fuses, output overvoltage, short-circuit, and overload protections. Hold up time is 17 milliseconds minimum at full load, nominal input voltage and power fail signal delay time is 1 millisecond minimum.
