2” x 4” Power Supply Delivers up to 150 Watts

TRUMPower has introduced the TMC150 series, which can generate up to 150W with 7.5 CFM forced airflow and 100W under convection cooling. Packaged in a 2 x 4 x 1.2 inch open-frame form factor, the series is an addition to the 40W, 60w, and 100W 2" x 4" open frame power supplies that the company has had on the market. It can be used in various end-user applications. The TMC150 series is approved by UL, cUL and TUV to 3rd edition EN 60601-1, IEC 60601-1, ANSI/AAMI ES 60601-1:2005 and CAN/CSA-C22.2 No. 60601-1:08 medical standards and to 2nd edition IEC/EN/UL 60950-1 ITE standards. The unit has a universal input range of 90- to 264-Vac, along with 0.98 typical power factor with active PFC.

The series meets 2 x MOPP and is designed for direct patient contact applications with its BF rated outputs. There are 7 standard models with output voltages 12V, 15V, 18V, 24V, 30V, 36V, 48V. The power supplies come with overvoltage and overcurrent protections. Withstand voltage is 4000-Vac from input to output, 1500-Vac from input to ground, 1500-Vac from output to ground. Earth leakage current is 105µA maximum at 264Vac, 63 Hz.

The TMC150 series is specified for full-load operation from 0 to +70 degrees C ambient, with no derating required until +50 degrees C and is suited for operating at up to 5,000 meters altitude. The series has an MTBF of 250,000 hours minimum at full load at 25 degrees C ambient, calculated per MIL-HDBK-217F. The power supply has remote sense and optional power failure detect signal (PFD).

No load power consumption is <0.5W without PFD and <1W with PFD. The units comply with EN61000-3-2 class A & D, EN61000-4-2, EN61000-4-3, EN61000-4-5, EN61000-4-11, in addition to EN55011, EN55022, FCC/VCC class B conducted and class A radiated EMC standards. It achieves an efficiency of 87-89% and is compliant with RoHS requirements.
