DESCRIPTION
The cPCI325D Series is a high-reliability, 325 watt
power supply for 3U Compact PCI™ systems.
Developed to support hot-swap, redundant
operation, the cPCI325D Series is designed for
compliance with PICMG™ 2.11 R1.0 Power
Interface Specification with 47-pin I/O connec-
tor. With integral IPMI functionality, this unit was
developed with high-availability (HA) telecommu-
nications applications in mind. Current sharing and
integral ORing FETs are included to support these
and other applications requiring reliable, hot-swap
performance and N+1 redundant configuration.
The high power density and complement of global
agency approvals provide for an advanced, high-
efficiency power solution for your CompactPCI™
system requirements.

Outputs are individually protected against overloads and indefinite short circuit with
automatic recovery upon removal of the fault condition. Overload response for outputs
V1-V3 is constant-current mode, with hiccup mode response to a hard short. Overload
response for V4 is linear foldback.
Outputs V1-V3 are capable of compensating >250mV of line drop. Unit automatically
reverts to local sensing in the event that the sense leads are opened for any reason. Unit
is protected against reversed or shorted sense leads.
Active droop current sharing on Outputs V1-V3. Accuracy better than 10% of maximum
rated load. Passive current sharing on output V4. Up to 8 units can be operated in a
parallel array.
1. Total regulation includes line, load and cross regulation.
