Datasheet

A series of medical grade power adapters that deliver many hard-to-find dual and triple output voltages have been introduced by TRUMPower. The TSM100 class I units meet 2 MOPP and are feature an IEC 320/C14 AC inlet and an optional power switch. The series comes with 25 dual and triple output models offering combinations of +3.3, +5, ±12, ±15, and ±24V at 55-80W output power.

The series also includes 70-100W single output models with the voltage factory preset anywhere between 5 and 40V. The standard single output models come with a four-pin power DIN output connector, while the standard dual and triple output models feature a five-pin or an eight-pin DIN plug. Other output connectors are available upon request.

Earth leakage current is 100µA maximum at 240VAC, 60Hz. The power supplies carry CE marking, are RoHS2 compliant and accept a 90 to 260VAC universal input with 0.95 power factor. Withstand voltage is specific at 5,656VDC (or 4000 VAC) from input to output and 2,121VDC (or 1500VAC) from input to ground. Operating from a -10 to +70°C ambient temperature range, the units are suitable for use at altitudes up to 3,000 meters. The MTBF is higher than 100,000 hours at full load and 25°C ambient per MIL-HDBK-217F. Output protections include short-circuit, over voltage and overload.

The TSM100 series is approved by TUV and UL to IEC/EN 60601-1 3rd edition, ANSI/AAMI ES 60601-1:2005 and CAN/CSA-C22.2 No. 60601-1:08 medical standards. The power supplies comply with EN60601-1-2 EMC and immunity standards including EN55011, FCC and VCCI Class B, EN61000-3-2, EN61000-4-2, EN61000-4-3, EN61000-4-5 and EN61000-4-11.
