DC-DC Converter

Product Details

The PQ50073HZB60 PowerQor Zeta Half-Brick converter is a next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter. The Zeta series offers industry leading power density for standard isolated DC/DC converters with both a wide input range and a tightly regulated output. Targeted for use in intermediate bus architectures, this module supplies an isolated step down voltage from 44-52V to 7.3V and provides 2,250Vdc isolation, tolerance of output current transients up to 85A, and more available power and higher efficiency than most competitive bus converters. RoHS compliant (see last page).
