SUPERVERTER
®
50/75/100/150/175 SERIES
36-175 WATTS
28VDC INPUT
1/2 BRICK
INDUSTRY STANDARD
DESCRIPTION
The SuperVerter 28 Series are high power
density and high dynamic response DC-DC con-
verters designed for use in telecom, wireless, and
other centralized modular or distributed power
systems using 24V input. The SuperVerter 28
family of DC-DC converters may be used as
form, fit, function replacements for the
industry standard half bricks.
