400W AC/DC power supply meets medical standards
The TMPC-400-1U is the latest 400W AC/DC power supply from Trumpower. The 1U ATX PC power supply measures 220 x 100 x 40.5mm and has over-voltage and over-load protection. 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 microA at 264V AC 63Hz, and is suitable for patient care.
The power supply is capable of operating at a temperature range between 0 and +60 degrees C and a high operating altitude of 5,000 meters maximum. The 400W rated power supply is equipped with a universal input range of 90 to 264V AC and DC voltage outputs and maximum loads of +3.3V/18A, +5V/18A, triple +12V/16A (18A peak), -5V/0.2A, -12V/0.5A, and +5Vsb/3A respectively. Maximum overall output is 400W, with +3.3V and +5V providing a combined maximum load of 100W.
Active efficiency is 87 per cent 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. The TMPC-400-1U is capable of being equipped to meet Intel’s Haswell power requirements. Withstand voltage is 4,000V AC between input to output (2MOPP) and 1,500V AC between input to PE (1MOPP). Mean time between failute is over 138,200 hours at full load at 25 degrees 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.
