The PQ60120QEA25 PowerQor Exa quarter-brick
converter is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter. The Exa 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).
