Platform Overview:
Xeta
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.
