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).
