Tumbler Technologies and TRUMPower has launched a 400W AC-DC medical power supply that meets 1U height restrictions.

The TMPC-400-1U ATX PC power supply measures 220 x 100 x 40.5 mm and includes over voltage and over load protections. The power supply meets the latest 3.1 edition of UL/IEC/EN 60601-1 medical safety standards and has a maximum earth leakage current of 150 μA at 264 VAC 63Hz, making it suitable for areas of patient care.

The TMPC-400-1U AC-DC medical power supply operates between 0°C and +60°C and a high operating altitude of 5,000 m. The universal input range of 90-264 VAC and outputs maximum loads of +3.3V/18A, +5V/18A, triple +12V/16A (18A peak), -5V/0.2A, -12V/0.5A, and +5Vsb/3A respectively. The maximum overall output is 400W, with +3.3V and +5V providing a combined maximum load of 100W. The combined maximum load for +12V1, +12V2, +12V3 must not exceed 32A.  The only minimum load required for the power supply is 0.1A for +12V3.

With an active efficiency of 87 percent minimum at full load, the power supply qualifies for 80 PLUS Gold energy efficiency and it also complies with ATX12V and EPS 1U 2.0 standards. It can withstand voltage is 4,000 VAC between input to output (2MOPP) and 1,500 VAC between input to PE (1MOPP). The supply is capable of over 138,200 hours MTBF at full load at 25°C ambient per MIL-HDBK-217.

The TMPC-400-1U is certified to the latest medical standards, including UL/IEC/EN 60601-1 (Edition 3.1), ANSI/AAMI ES 60601-1:2012, and CSA C22.2 No. 60601-1:2014. The power supply complies with IEC/EN 60601-1-2 4th edition medical EMC and immunity standards including EN 55011, CISPR11/FCC, VCCI class B (conducted and radiated emissions), EN 61000-3-3, EN 61000-4-2, EN61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, and EN 61000-4-11.
