QSC150 Series

150W 4:1 quarter brick DC-DC converters for railway & industrial electronics applications

The QSC150 series offers a compact 150W DC-DC converter solution in an industry standard quarter brick package. This series of modules is available in two input ranges, covering 9 to 36VDC & 18 to 75VDC that enables effective construction of distributed power architectures.

Utilizing the integral baseplate for conduction cooling gives the designer flexibility in system design, with an industrial operating temperature range -40°C to +105°C and includes protection for over current, over temperature and over voltage.

Complies with railway standards EN50155 and EN45545-2. In addition to railway applications the QSC150 is highly suited to telecommunications, distributed power architectures, battery operated equipment, industrial electronics, mobile equipment and many other applications.
