Platform Overview:
VetaiHA48 Series DC-DC Power Modules
48V Input, 1.2-28V/60A or 350W Output
Half-Brick
The VetaiHA48 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. Its high
efficiency and superior thermal performance make
the VetaFamily of power modules ideally suited
for power-hungry applications in demanding
thermal environments. This rugged building block
is designed to serve as the core of your high
reliability system. A wide output voltage trim range
and remote sensing are standard features
enhancing versatility.
