It has been announced by TRUMPower that its TSA42 power adapter series are compliant with DOE level VI. Measuring 146x76x43mm, the TSA42 units are furnished with an IEC 320/C14 AC inlet and a power-on indicator. The series comes with 16 dual and triple output models offering combinations of +3.3, ±5, +5.1, +7.2, ±12, ±15 and ±24V at 23.82-42W output power.

It features 80-84% efficiency at full load and 0.3W no-load power consumption. Standard output connector is a 5-pin DIN plug but alternative output connectors are available upon request.

The power supply is approved to UL/IEC/EN 60950-1 2nd edition safety standards and it is UL, cUL, CB, CE, TUV/GS, PSE approved. The unit complies with EMC and immunity standards including EN55022, FCC Class B, EN61000-3-2, EN61000-4-2, EN61000-4-3, EN61000-4-5, EN61000-4-11, etc.

The power supply is RoHS compliant and accepts a 90-264VAC universal input. Withstand voltage is specific at 4,242VDC from input to output and 2,677VDC from input to ground. The units can operate at 0 to +70°C ambient temperature (de-rating applies above 40°C) and the MTBF is higher than 100,000 hours at full load, 25°C ambient calculated per MIL-HDBK-217F. Output protections include short-circuit, over voltage, and over load.

The TSA42 series is competitively priced in OEM quantity. TRUMPower offers a wide selection of ITE and medical grade power adapters ranging from 4W-400W that meet level VI efficiency standards.RUMPower has been delivering excellent quality medical and industrial grade AC/DC switching power supplies and DC/DC converters since 1991.
