Powerful new 1,000W medical-grade power supply

Tumbler Technologies, Inc. + TRUMPower has unveiled its new TMPC-1000 power supply with no minimum load needs and up to 2,000W peak power capability. This 1,000W medical ATX PC power supply has dimensions of 165mm x 150mm x 86mm and fulfils the latest medical 60601-1 and ITE 62368-1 safety standards. The dual approvals for the power supply permit it to be employed in various industrial and medical applications needing high power output.

The 1,000W rated power supply functions at a high operating altitude of 5,000m maximum. It is equipped with DC voltage outputs and maximum loads of +3.3V/25A, +5V/25A, +12V/83.3A, -12V/0.5A, and +5Vsb/3.5A respectively. While not standard for this model, adding a -5V/0.2A output is available upon request. Its maximum overall output is 1,000W, with +3.3V and +5V providing a combined maximum load of 150W. The maximum output power for +12V must not exceed 1,000W.

The power supply complies with 80PLUS GOLD efficiency standards and ATX12V V3.0 standards. It has BF class isolation and withstands voltages of 4,000VAC for input to output (2MOPP), 1,500VAC for input to ground (1MOPP), and 1,500VAC for output to ground. The highly reliable power supply is capable of over 100,000 hours MTBF at full load, 25C ambient, calculated per MIL-HDBK-217F.

The TMPC-1000 is certified to the latest medical standards, including UL/IEC/EN 60601-1 (Edition 3.2), ANSI/AAMI ES 60601-1:2005/A2:2021, and CAN/CSA-C22.2 NO. 60601-1:14/A2:22 (R2022). It is also certified to IEC 62368-1 (3rd edition). The power supply complies with IEC/EN 60601-1-2 edition 4.1 medical EMC and immunity standards including EN 55011/EN55022, FCC/VCCI class B (conducted and radiated emissions), EN 61000-3-2, 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.
