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-in.), and having pin out compatibility with existing industry standards. The QSB150 is efficient up to 92% and is 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 to 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 to 100°C.
