Medical Grade 4:1 DC/DC packs 60W in miniature package

The cost-effective REM60-W is available with two input ranges, 9-36VDC, and 18-75VDC, each with a selection of tightly regulated single and dual outputs: 5V, 5.1V, 12V, 15V, 24V +/-12V, and +/-15V. The case size of the DC/DC is just 2.3” x 1.5” x 0.5” (57.9 x 36.8 x 12.7mm) achieving industry-leading power density for a 60W part. Thanks to their excellent efficiency, peaking at over 90%, the DC/DCs operate to 105°C ambient with derating, or as an example, to 83°C at full 60W output power with 2m/s airflow (REM60-4824SW variant).

The REM60-W series has reinforced/ 2MOPP isolation, rated 5kVAC/1min for 250VAC working voltage, with creepage and clearance distance from input to output of more than 8mm. Patient leakage current is 4.5µA maximum to suit medical B, BF, and CF applications.

Medical safety certifications include IEC/EN 60601-1 3rd edition as well as ANSI/AAMI ES60601-1 and CAN/CSA-C22.2 No. 60601-1:14 for the North American markets. The parts are also compliant with EN 60601-1-2 for EMI immunity for medical equipment. IEC/UL/EN 62368-1 certifications are also held for the IT/multimedia markets and EMC standards EN 55032 Class A and B can be met with a simple external filter. The REM60-W series is characterised for the operation to 5000m altitude and for a pollution degree 2 (PD2) environment. Reliability is also high at over 1Mhrs MTBF according to MIL-HDBK-217F, 25°C, Ground Benign conditions.

The REM60-W series includes an On/Off control, remote sense, and output voltage trimming with full protection against over-temperature, output overloads, short circuits, and input under-voltage. Operation to zero load is possible, light load efficiency is high, and quiescent and standby current is low. Pin-out is industry standard.

“The REM60-W is a high-specification, power-dense part which will be appreciated in medical and demanding industrial applications” – Matthew Dauterive, DC/DC product manager at RECOM
