CPCI500DC Datasheet, PDF (2/4 Pages) C&D Technologies – 500 Watt, 6U x 4HP, Compact PCI

SPECIFICATIONS, ALL MODELS
Transient Response
For a step load change of 50%-100%-50%, the peak output
excursion will not exceed 8% of nominal voltage, and will
recover to within 1% of nominal voltage within 200
microseconds.
Current Share
Active current sharing is employed on Outputs V1, V2 and V3.
Remote Sense
Outputs V1, V2, and V3 are capable of compensating up to
0.3VDC 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.
Output Power
500W continuous maximum, with 400lfm airflow at a
maximum ambient of 50°C.
Overload Protection
Outputs are individually protected against overloads and
indefinite short circuit with automatic recovery upon removal
of the fault condition.
Over Voltage Protection
All outputs have over voltage protection at 125% typical
(135% max.) of nominal.
Over Temperature Protection
Outputs are individually protected against over temperature.
Outputs will automatically restore upon recovery to
acceptable temperatures.
Output Fault Isolation
Output isolation diodes are present in all outputs to isolate
faults within a failed power supply.
IPMI Option
2
An I C board is available as a factory-installed option to
provide an IPMI interface to the SM bus. Status functions
include output voltage and current levels as well as the DEG
warning. Output inhibit control can be toggled under software
command. See Application Note ACAN-02 for satellite
controller specification, ACAN-03 for firmware update
procedure and ACAN-04 for test procedure.
Remote Inhibit (INH#)
Secondary referenced, active low, TTL compatible signal
inhibits all outputs upon activation.
Power Fail Warning (FAL#)
Open collector signal indicates output failure. Active low.
Enable (EN#)
Short pin on connector will enable power supply output when
the mating pin is grounded. Supply will not power up until
this pin is engaged to its mate in the backplane. Unit output
will be inhibited as pin is disengaged from the mating
connector.
Temperature Warning (DEG#)
Open collector indicates internal temperatures are approaching
the thermal shutdown limit. Active low.
Fault Indicator LED
A red LED will be ON if output voltages are not within
specification.
Power Present LED
A green LED will be ON when input voltage is present and
above the minimum requirement.
Cooling
400lfm of airflow required to maintain full output power at 0-
50°C ambient. Additional data on operation below 400lfm is
available in Application Note ACAN-01.
Temperature
Full output power achievable over the range of 0-50°C.
Storage temperature limits are –20 to +85°C. Additional data
on operation above 50°C is available in Application Note
ACAN-01.
Altitude
Operating: -200 to +10,000 feet with ambient temperature
derating above 5,000 feet in accordance with the adiabatic
lapse rate.
Inhibit Indicator LED (Yellow)
A yellow LED will be ON when the outputs are inhibited.
