XP Power announced the QSB150 series of 150 Watt half brick DC-DC converters aimed at a wide range of applications where an ultra-wide input range are 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 ultra-wide 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 a wide range of environments and temperatures from – 40 degrees C to a maximum base plate temperature of + 100 degrees C.
The QSB150 complements the exiting QSB range of 75-600 Watt base plate cooled modules in quarter brick, half brick and full brick packages with 2:1 and 4:1 input ranges and comes with a 3-year warranty.
