DC-DC converter designed for harsh environments

19 September 2007 Power Electronics / Power Management

XP Power's new MQP120 range of isolated DC-DC converters has been specifically designed for systems that need to be powered from both 12 V d.c. and 24/28 V d.c. electrical supplies. The converter accommodates a wide range of input voltage, from 9 to 40 V d.c., and is rated to 120 W. Five standard output options are available, supplying voltages of 3,3, 5, 12, 15 and 24 V d.c.

The MQP120 is fully encapsulated, making the unit resistant to the effects of dust as well as vibration and shock. The unit is compact at just 95 x 11,5 x 65 mm, and has a power density of 1,63 watts per cubic centimetre. It has an operating temperature range of -40°C up to a baseplate temperature of +100°C, while an optional heatsink is available to simplify thermal design should cooling via the baseplate prove insufficient.

Typical systems that might use the MQP120 series include communications, sensors and weapon systems on military platforms. The series meets military standards for electro-magnetic and electrical immunity.
