The cPCI420DC is a high-reliability,420 watt power supply for 6U Compact PCI? systems. Developed to support hot-swap, redundant operation, the cPCI420DC is designed for compliance with PICMG? 2.11 R1.0 Power

Interface Specification with 47-pin I/O connector, as well as the underlying CompactPCI? standards. Operating from 36-72V 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+1redundant configuration. The 8HP package and complement of agency approvals provide for a complete power solution for your CompactPCI? system requirements.

* Combined currents from outputs V1 & V2 not to exceed 60A.

Current S hare

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 S ense

Outputs V1, V2, and V3 capable of compensating up to

0.5VDC 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

420W continuous maximum, with 400lfm airflow at a maximum ambient of 50°C. See Derating Chart on page 3 for additional data.

Overload Protection

Outputs are individually protected against overloads and indefinite 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. Output V3 OVP set at 13.5 +0.5V DC. Output V4 OVP set at -13.5 +0.5V DC. The power supply will shut down and latch off under an OVP fault condition. Restart of the unit is accomplished 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 automatically 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.

S ynchronous S tart

Interconnection of the Sync Start pin (pin 23) ensures that the outputs of parallel supplies will be enabled simultaneously to ensure sufficient source current in applications where the load current exceeds the capacity of a single power supply module. Remote Inhibit (INH#)

Secondary referenced, active low, TTL compatible signal inhibits all outputs upon activation.

Power Fail Warning (FAL#)

Secondary referenced, active low, TTL compatible signal indicates 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 connector.

Temperature Warning (DEG#)

Open collector indicates internal temperatures are approaching the thermal shutdown limit.

Fault Indicator

Red LED will be ON if output voltages are not within specification.

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 0-50°C ambient. See Derating Chart below for additional data. Temperature

0-70°C operating range with full output power achievable over the range of 0-50°C. See Derating Chart below for additional data. Storage temperature limits are –20 to +85°C. Altitude

Operating: -200 to +10,000 feet with ambient temperature derating above 5,000 feet in accordance with the adiabatic lapse rate.

PIN ASSIGNMENT: Pin assignment consistent with PICMG ? 2.11R1.0 specification. The table below details the PICMG ? assignment.

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)PICMG ? 2.11 has reserved Pin 23 for future designation -- the cPCI420 uses this pin for synchronous start, required when N>1

for N+1 redundant configurations.

(4)This function not available in the cPCI420DC.
