Maxeta iFA Series DC-DC Power Modules
24V Input, 28V Output, 602W Full Brick
The Maxeta
iFA series power modules are
ideally suited for wireless applications to power
RF power amplifiers. With a typical 89% full
load efficiency (90% at 80% load), a power
density of 108W per cubic inch and a total
power and current output capability of 602W
and 21.5A respectively, the Maxeta
Series
offers the highest efficiency, power density and
usable output power for 24V input applications
in a standard full brick package currently
available. A wide output voltage trim range, -
40% to +10%, remote sensing, and isolated
remote on/off control are standard features
enhancing versatility. The Maxeta
iFA series
power modules are also suited for other
telecommunication applications.
