Description
The ultra-compact FE5A Series Front-End Power Supply provides a single isolated output of up to 5000-Watts
with inputs ranging from 365 Vac to 528 Vac, 3 phase, and can handle frequencies from 47 Hz to 63 Hz. Designed
for high current applications requiring a compact size. The FE5A series operates either as a standalone unit or as
part of rack-mounted power systems. The supply provides true front-end capability to automatic test equipment,
telecom, data communications, and other distributed power designs.

Signals and Controls
LED Output Good Indicator:
Front panel green LED
indicates power supply is good; amber indicates fault.
LED AC Good Indicator:
Front panel green LED indicates
Ac input voltage is present and above minimum level.
Output Good Signal*:
TTL compatible signal, normally high.
Goes low when power supply is out of specified range.
Power Fail Signal*:
TTL compatible signal, normally high
(indicating Vin is present and above minimum level).
Enable*:
Normally TTL High, drive low to enable.
*All interface signals are TTL compatible
