XP Power announced the QSB150 series of 150 Watt half brick DC-DC converters aimed at a range of applications where an ultra-wide input range is required. Conforming to the industry standard half brick footprint of 61.5 x 57.9 x 12.7 mm (2.40 x 2.28 x 0.50 inches), and having pin out compatibility with existing industry standards, the QSB150 is highly efficient, typically up to 92 %. Available in six regulated single output models, covering all the popular nominal output voltages from + 12 to + 48 VDC, a voltage trim function allows adjustment of +/-10 % of stated output if required to accommodate line losses or non-standard voltage requirements.

With an input range of 9-75 VDC, these units accept all nominal inputs of 12, 24 and 48 VDC. By accepting three nominal battery voltages, using the QSB150 negates the need for a change in end equipment.  Input to output isolation is 1,500 VDC. A remote on / off input provides a method of sequencing start up and providing external control of the unit.

The QSB150 can operate in temperatures from – 40 degrees C to a maximum base plate temperature of + 100 degrees C.
