cPCI200-DC REV A 7/2003

Product: www.cdpoweronline.com

Transient Response

For a step load change of 50%-100%-50%, the peak output

excursion will not exceed 10% of nominal voltage, and will

recover to within 1% of nominal voltage within 500 microseconds.

Current Share

Active current sharing on Outputs V1and V2. Accuracy better than

10% of maximum rated load. Primary referenced.

Remote Sense

Outputs V1and V2 are capable of compensating >50mV 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

180W (Output configuration A) / 225W (Output configuration

B) continuous maximum, with 300lfm airflow at a maximum

ambient of 50°C. Derate to 90W/110W at 70°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

Outputs V1 and V2 have Over Voltage Protection at 125% typical

(135% max.) of nominal.

Over Temperature Protection

Outputs are 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.

Remote Inhibit (INH#)

Secondary referenced, active low, TTL compatible signal inhibits

all outputs upon activation.

IPMI Option

Available on Models cPCI200D-3 and cPCI200D-4

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. For a

complete specification of the firmware solution refer to

Application Note ACAN-02 on our website.

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 (+/-10°C, typ). 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

300lfm of airflow required to maintain full output power at 0-

50°C ambient.

Temperature

Full output power achievable over the range of 0-50°C. 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 (approximately 2C per 1000 feet).

Inhibit Indicator LED (Yellow)

A yellow LED will be ON when the outputs are inhibited.

Complies with IPMI V1.5 Rev 1.1 and IPMB V1.0

Complies to PICMG 2.9 (CompactPCI Systems Manage-

ment Specification)

8 analog inputs configured for monitoring voltages and currents

on power supply outputs V1 - V4

Monitors the state of the thermal sensor

Output inhibit can be controlled by IPMI commands

Self Test with LED indicator (can be read and overridden

by IPMI commands)

6 programmable thresholds on each analog sensor

Each threshold on each sensor can be enabled to generate

event messages if that threshold is crossed

Thermal sensor can be enabled to generate event messages

Responds to all mandatory IPMI commands and numerous

optional commands as indicated in the functional specifi-

cation

Firmware can be upgraded via the IPMB bus

Includes Device SDR’s (Sensor Data Records) - These

specify the type of sensor for each input (voltage, current,

temperature, etc.) as well as the conversion formulas from

raw ADC data to voltages, currents, etc.

Includes FRU data such as model number, serial number

and firmware creation date
