systems. Developed to support hot-swap, redundant operation, the cPCI350DC is
designed for compliance with PICMGTM 2.11 R1.0
Power Interface Specification with
47-pin I/O connector, as well as the underlying
CompactPCITM standards. Operating
from 36-75V
DC
, this unit was developed with high-availability (HA) telecommunications
applications in mind. Active current sharing and internal ORing diodes are included to
support these and other applications requiring reliable, hot-swap performance and N+1
redundant configuration. The 8HP package and complement of agency approvals provide
for a complete power solution for your CompactPCITM system requirements.

Remote Inhibit (INH#)
Secondary referenced, active low, TTL compatible signal in-
hibits all outputs upon activation.
Power Fail Warning (FAL#)
Secondary referenced, active low, TTL compatible signal in-
dicates output failure.
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 con-
nector.
Temperature Warning (DEG#)
Open collector indicates internal temperatures are approach-
ing the thermal shutdown limit.
Fault Indicator
Red LED will be ON if output voltages are not within specifi-
cation.
Power Present LED
Green LED will be ON when input voltage is present and
above the minimum requirement.
Cooling
400 lfm of airflow required to maintain full output power at 0-
50C ambient. At 200 lfm, the output power is derated to
175W.
Temperature
0-70C operating range with full output power achievable over
the range of 0-50C. Between 50C and 70C, output power
derates linearly from 350W to 175W. Storage temperature
limits are 20 to +85C.
Altitude
Operating: -200 to +10,000 feet with ambient temperature
derating above 5,000 feet in accordance with the adiabatic
lapse rate.

Current Share
Active current sharing is employed on outputs V1, V2, and
V3. Accuracy exceeds 10% of maximum rated load. N
max
=
4. Output V4 to share within 40% of maximum rated load by
means of droop response.
Remote Sense
Outputs V1, V2, and V3 capable of compensating up to
0.5VDC of line drop. Unit automatically reverts to local sens-
ing in the event that the sense leads are opened for any
reason. Unit is protected against reversed or shorted sense
leads.
Output Power
350W continuous maximum, with 400lfm airflow at a maxi-
mum ambient of 50C. Output power derates linearly to 175W
at 70C ambient or 200lfm of airflow at 50C.
Overload Protection
Outputs are individually protected against overloads and in-
definite short circuit with automatic recovery upon removal
of the fault condition.
Over Voltage Protection
Output V1 OVP set at 6.0V 0.5V
DC
. Output V2 OVP set at
4.3V 0.5V
DC
. The power supply will shut down and latch
off under an OVP fault condition. Restart of the unit is ac-
complished by cycling of the input power.
Over Temperature Protection
Thermal switch shuts down the power supply in the event
that critical temperatures are exceeded. Unit will automati-
cally restart when acceptable temperatures are restored.
Output Fault Isolation
Output isolation diodes are present in all outputs to isolate
faults within a failed power supply.

PIN ASSIGNMENT:
Pin assignment consistent with PICMGTM 2.11R1.0 specification.
The table below details the PICMGTM assigment.
NOTES: (1) Pin numbers correspond to the female backplane connector.
(2) L = Long Length Pin (First Make, Last Break); M = Medium Length Pins; S = Short Length Pins (Last Make, First Break)
(3) PICMGTM 2.11 has reserved Pin 23 for future designation -- the cPCI350 uses this pin for synchronous start, required when N>1
for N+1 redundant configurations.
(4) This function not available in the cPCI350DC.
NOTES:
All measurements are in inches.
CONNECTOR:IEC Number is pending.
