Powerbox Releases 105 DC/DC Converters Models with 2xMOPP Medical Approvals

June 3, 2019 Alix Paultre

Powerbox introduced three series of 15W, 20W, and 30W board-mount DC/DC converters for demanding medical applications, totaling 105 models. The PMM15, PMM20 and PMM30 are certified to the 3rd Edition of the IEC/EN/ANSI/AAMI ES 60601-1 medical safety standard and rated for 2xMOPP. With a clearance and creepage distance of 8mm, a typical leakage current of 2µA, and a 5,000VAC isolation voltage, the modules are available in wide input (2:1) and ultra-wide input (4:1) versions covering from 9V to 75V input voltage and providing seven different output voltages from 5V to +/-15V.

The PMM15, PMM20 and PMM30 have an input to output isolation voltage of 5,000VAC, and integrate a reinforced insulation with two means of patient protection (2x MOPP), a typical leakage current of 2µA, and a clearance and creepage distance of 8mm. The PMM15, PMM20 and PMM30 wide input (2:1) units are available in three input voltage ranges, 9-18V, 18-36V, 36-75V, and the ultra-wide input (4:1) versions in two input voltage, 9-36V and 18-75V. All models are fully regulated with a complete range of output voltages comprising 5V, 12V, 15V, 24V, +/-5V, +/-12V and +/-15V. No minimum load is required and tight regulation from no load to full load of +/-0.2% on single output, and +/-0.5% on dual output is provided.

The PMM15, PMM20 and PMM30 have an efficiency up 90 percent and can be operated within an ambient temperature of -40 to +105 degrees C. In the case of natural convection, a derating may apply. In cases of excess heat, an internal over-temperature protection is set at +115 degrees C case. Protections include over-voltage, under-voltage, overload and short circuit, and thermal-shutdown. Supplied in a non-conductive black plastic housing and potted with a UL94-V0 silicon compound, the PMM15 and PMM20 are sized at 40.6 x 25.4 x 10.2 mm (1.6 x 1 x 0.4 inch) and weigh 24 grams. The PMM30 is available in a 50.8 x 25.4 x 10.2 mm (2.0 x 1.0 x 0.4 inch) housing and weighs 32 grams.
