QHL300 Series

300W half brick 300VDC input baseplate cooled DC-DC converters

The QHL300 series provides a compact 300W DC-DC solution in an industry standard half brick package with a nominal 300VDC input and an operating range of 180 to 425VDC. This series of modules enables effective construction of distributed power architectures from AC front ends, PFC front ends, baseplate cooled ESG solutions and high voltage battery applications.

Utilizing the integral baseplate for conduction cooling gives the designer flexibility in system design. Constructed with reinforced insulation, the QHL series features an industrial operating temperature range and includes protection for over current, over temperature and over voltage.
