Military approved power supplies

18 February 2009 Power Electronics / Power Management

XP Power has announced the launch of its MCM series of rugged, metal-cased convection-cooled power supplies that are designed for deployment in harsh and physically demanding environments. In addition, the series offers EMI performance to MIL-STD 461E/F standards, conducted and radiated, for emissions and susceptibility. Sealed against dust and water, the unit’s metal case is equipped with fixing holes for mounting on an equipment shelf or fitting inside customer equipment. The casing also helps to dissipate heat, allowing the unit to operate at high temperatures.

Five models are available within the series, providing output voltages of 12, 15, 18, 24 or 28 V d.c. Input voltage is in the range of 90–264 V a.c. or 120–370 V d.c. The supplies operate at full output power between -40 and +50°C and derate linearly to 50% load at +70°C. The units comply with UL60950-1 and EN60950-1 safety approvals for industrial, commercial and IT equipment.

Measuring 139,7 x 69,8 x 37,6 mm, the unit has a 5-pin DIN plug standard output connector. Optional output connectors include D-Sub, Lemo Barrel, customer specific or no connector. Typical applications include defence, geo-physical, heavy industrial, secure communications and mobile computing.
