iHG48 Series DC-DC Power Modules

48V Input, 3.3V / 70A Output
Half-Brick

The Xeta



iHG48 Series power modules operate

over a wide 36 – 75Vdc input voltage range and
provide one regulated dc output voltage that is
electrically isolated from the input. The single
board

open-frame

type

design

with

high

conversion efficiency (up to 92%), and superior
thermal performance make iHG series modules
ideally suited for high power, low air flow telecom
applications in demanding thermal environments.
A wide output voltage trim range, -50 to 10%, and
remote sensing are standard features enhancing
versatility.
