DESCRIPTION
The PFE850-12-054xA is an 1100 Watt AC to DC power-factor-
corrected (PFC) power supply that converts standard AC mains power
into a main output of 12 VDC for powering intermediate bus architec-
tures (IBA) in high performance and reliability servers, routers, and
network switches. The PFE850-12-054xA meets international safety
standards and displays the CE-Mark for the European Low Voltage
Directive (LVD).
APPLICATIONS
o HIGH PERFORMANCE SERVERS
o ROUTERS
o
SWITCHES
