Tumbler Technologies + TRUMPower have introduced the TMP60 series of medical grade AC/DC desktop power adapters, which deliver up to 60W of output power. Conforming to CEC and Energy Star level IV requirements, these power adapters (single output models) have an efficiency of 85% or greater and standby power consumption less than 0.5W. Earth leakage current on the power adapters is 90µA at 115VAC/60Hz or 150µA at 230VAC/50Hz. The units also meet RoHS requirements. The TMP60 series is approved by EN 60601-1, UL 60601-1 and CSA C22.2 No. 601.1 medical standards and complies with EN60601-1-2 EMC standards including EN55011/FCC/VCCI class B, EN61000-3-2, EN61000-4-2, EN61000-4-3, EN61000-4-5, EN61000-4-11, etc.
This series includes single, dual and triple outputs. On single output models, the output can be preset between 11-39V and 46-50V during production. Dual and triple output models offer combinations of +3.3V, +5V, ±12V, ±15V, and +24V outputs. Enclosed in a 94V-1 rated polyphenylene-oxide case with dimensions of 2.95x5.79x1.65 inches, the units come with a 5-pin DIN plug as the standard output connector and an optional power switch.
The power adapters incorporate 85 to 264VAC wide input and a built-in IEC 320/C14AC inlet mating with different types of AC power cords. The series has overvoltage protection, which is set at 112-140% of its nominal output voltage and provided only on output 1. Overcurrent protection is supplied on all outputs protected to short circuit conditions. The power adapters contain a LED indicator and they operate between 0°C and +60°C, with derating required starting at +40°C. The withstand voltage is 4000VAC from input to output, 1500VAC from input to ground, 500VAC from output to ground. The series has a calculated MTBF of minimum 150,000 hours at full load at 25°C ambient per MIL-HDBK-217F.
