Half brick 150 W DC-DC converters

- Advertisment -

 

XP Power recently announced the QSB150 series of 150 W 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, 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 DC, 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 DC, these units accept all nominal inputs of 12, 24 and 48 V DC.  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 DC. A remote on/off input provides a method of sequencing start up and providing external control of the unit.
