DESCRIPTION
The PCI500-4D is a modular, hot-swap, 500W, quad
output power supply with wide range 48Vdc input.
This unit was designed specifically for redundant
applications with active current sharing, synchronous
starting, and output isolation diodes.

The PCI500-4D incorporates a unique architecture
that supports migration of low-voltage requirements
between the 5V and 3.3V rails by deriving both of these
outputs from a common transformer winding.

The PCI500-4D is ideal for networking equipment,
communications, and computer equipment where
fault-tolerance is a necessity. All outputs have remote
sense and are individually protected against overloads
and short circuits. With UL/cUL approval to ULꢀ950,
VDE approval to EN60950, and the CE Mark, the
PCI500-4D provides a truly global power solution for
your PCI requirements..

Notes:
ꢀ. Total regulation includes line, load, and cross regulation.
2. Combined current output of Vꢀ & V2 not to exceed 83A total.
Outputs Vꢀ, V2, and V3 share a common return. Outputs V4 has
an isolated return.
