®
The PQ60120HZA50 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 35-75V to 12V and provides
more available power and higher efficiency than most
competitive bus converters. This converter is available
in open-frame and baseplated versions. RoHS Compliant
(see page 13).
