• Description: AC/DC Compact PCI Power Supply
• Manufacturer: CANDD [C&D Technologies]

CONTROL/ALARM SIGNALS
Remote Inhibit: Referenced to RTN (Logic), Pin 40 or 43.
The power supply is off when the Remote Inhibit is less
than 1V, typical.
Power Present LED:
A green LED will light when AC is applied and exceeds mini-
mum operating limits.
DC Good Indicator:
A green LED will be illuminated when all outputs are be-
tween 90% and 110% (typical) of their nominal output volt-
age and extinguish when any voltage is out of this range.
Fan Fail:
TTL level signal goes low when fan fails. Referenced to RTN
(Logic), Pin 40 or 43. A green LED gives a visual indication
that the fan is operational.
DC OK:
An open collector output signal with an internal 2.2K pull
up resistor is connected to the +5V output. TTL signal will
go high when all outputs are between 90% and 110% of
their nominal output voltage.
Sync Start
A power supply generated signal used to simultaneously
start supplies operated in parallel. These pins must be tied
together at the backplane in parallel/redundant (N+0 or N+n)
applications when N>1. In simple redundant (1+1) or non-
parallel (1+0) applications, the pin can be ignored.
Current Share Bus
A power supply generated signal used to force current shar-
ing between supplies operated in parallel (V1 and V2). These
pins must be tied together at the backplane (5V CS to 5V

Hot Swap Enable
This pin must be tied to the DC GND at the backplane for
the power supply to operate. Since this pin is staged as the
shortest in the connectors, it is a “last-make/first break”
pin.
Power Supply Present
This pin presents a DC ground signal to the mating pin in
the backplane. It is intended to be used by the system to
detect if a power supply module is plugged into an available
position.
OUTPUT PROTECTION
Over Current/Short Circuit Protection:
Outputs individually protected against overload and indefi-
nite short circuit; automatic recovery after removal of fault.
Over Voltage Protection:
Output #1: 6.5V
Output #2
Over Voltage Protection will latch the power supply off until
input power is cycled.
Power Limit:
Auto recovery; at 530W output power typical, the unit will
cycle.
Reverse Voltage Protection:
All outputs protected up to rated current.
Over Temperature Protection:
Over Temperature shutdown with automatic recovery.
