New from XP Power is the QSB150 series of 150 Watt half brick DC-DC converters aimed at a wide 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, 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 V d.c., 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 V d.c these units accept all nominal inputs of 12, 24 and 48 V d.c. By accepting three nominal battery voltages, using the QSB150 negates the need for a change in end equipment. Input to output isolation is 1500 V d.c. A remote on / off input provides a method of sequencing startup and provides external control of the unit.
The QSB150 can operate in a wide range of environments and temperatures from -40°C to a maximum base plate temperature of +100°C. It comes with a 3-year warranty.
