Tumbler Technologies + TRUMPower features the medical grade TMC650 series of 600-650WAC/DC switching power supplies that is BF rated featuring an operation altitude of up to 5000 meters.
The series is designed to meet IEC/EN/UL 60601-1 Edition 3.1, ANSI/AAMI ES 60601-1:2012, CSA C22.2 No. 60601-1: 2014 and the 2nd edition of IEC/EN 60950-1. Withstand voltage is 4000VAC from input to output (2 MOPP), 1500VAC from input to ground (1 MOPP), 1500VAC from output to ground (1 MOPP). Earth leakage current is 300µA maximum @ 264VAC, 63Hz.
The series includes 12 standard single output models between 12-58V, delivering 600-650W of continuous power @ 30 CFM forced air, each of which accepts an input voltage of 90-264VAC. All models may be operated at no-load without damage with the output voltage fluctuating beyond 5% due to the burst-mode operation of the IC control for energy saving purposes.
Having comprehensive protection circuitry, the power supply includes over-voltage, over-current, short circuit, and thermal protections. Additional standard features include PFD, remote sense, output inhibit, and 5VDC standby power. The units can be fully loaded at -10 to +50°C ambient, with derating required from 100% at +50°C linearly to 50% at +70°C. The series offers high reliability with its 250,000-hour minimum MTBF at full load, 25°C ambient, calculated per MIL-HDBK-217F.
The TMC650 complies with IEC/EN 60601-1-2 4th edition medical EMC and immunity standards including EN 55011/FCC/VCCI class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-4-2 (ESD at 15kV air and 8kV contact), EN 61000-4-4, EN 61000-4-5, EN 61000-4-8, EN 61000-4-11. It achieves an efficiency of 90% typically and is compliant with RoHS requirements. Packaged in a 4x8x2.46” size, the units are constructed on a circuit board that contains a U-bracket for mechanical support and heat sinking. A cover and fan assembly is optional and can be added during manufacturing if user requires the enclosed form factor.
