XP Power today 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- 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 1,500Vdc. 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.
