Description
The PAC3000S12-CE converts an AC input of 90 V
to 264 V into a 12 V DC, 3000 W output. It provides
PMBus communication ports, communicates with
and sends the electronic serial numbers to the host
to facilitate the monitoring and management. Up to
eight PAC3000S12-CEs can be paralleled for
redundant configurations.

condition. The configuration diagram of PSON

PS_KILL
The PS_KILL pin help to implement the PSU
hot-plug. The PS_KILL input is active-low and is
located on a recessed pin on the connector and is
used to disconnect the main output as soon as
the power supply is being plugged out. This pin
should be connected to signal GND in the system.

PS_INTERRUPT will be low if one of the following
situations occurs:
• Input undervoltage (Delay time from ACOK low
to PS_INTERRUPT high will be less than 100
μs.)
• Input overvoltage (Delay time from ACOK low to
PS_INTERRUPT high will be less than 100 μs.)
• Output overvoltage
• Output overcurrent
ACOK
ACOK is an open collector signal to indicate that
the AC input has been removed for a time
sufficiently long, or when the AC input voltage falls
below regulation limits, ACOK is asserted to a low
state. About the detail of regulation limits is as
following:
• Overtemperature or undertemperature
• Fan fault

Remote sense
Load sharing
12 V DC output has sense lines implemented to
compensate for voltage drop on load wires. The
maximum allowed voltage drop is 0.2 V.
Up to eight PAC3000S12-CEs can be paralleled
for redundant configurations. All the I_Monitor pins
need to be interconneted in order to activate the
sharing function.
12 V
Protection Characteristic
Sense+
Output Overvoltage Protection
When the output voltage exceeds the output
overvoltage protection threshold, the PSU will
enter a latch off mode. The latch can be cleared
by toggling the PSON signal or by an AC input recycle. The delay time from PSON high to PSON
low should be more than 1 s. The delay time from
AC off to AC on should be more than 15 s.
Load
SenseGND
Figure 14: Configuration diagram for remote sense
Output Overcurrent Protection
1.After the remote sense is applied, the volt at the output
terminal is less than 12.8 V DC.
2. If the sense pin is not used, it should be left open.
Internal Cooling Fans
Power supply will power for the internal fans. It
contains fan speed control circuits to vary the fan
speed. If one of the paralleled PAC3000S12-CEs
has no output while the communication remains
normal, the fan can operate at minimum speed.
Figure 15 shows the detail about the wind tunnel.
Fan
When the output current exceeds the output
overcurrent protection threshold, the PSU will enter
a latch off mode. Output overcurrent shall be
maintained for a period of 1s before the PSU enter
a latch off mode. The latch can be cleared by
toggling the PSON signal or by an AC input recycle. The delay time from PSON high to PSON
low should be more than 1 s. The delay time from
AC off to AC on should be more than 15 s.
Overtemperature Protection
The power supply is protected against over
temperature conditions caused by loss of fan
cooling or excessively high ambient temperature.
In an overtemperature condition, the PSU shuts
down, the DCOK goes low and the bi-color LED
changes from green to red. When the fault
condition is removed, the PSU will automatically
restart.

connected to system backplane which is providing 12 V DC power, unit FRU data shall be accessible without
AC inputs.
Pins A0, A1, and A2 are also allocated at the power supply connector for selecting the PMBus address of

Monitoring functions:
• Input voltage
• Input current

• Output voltage
• Output current
• output power
• output voltage setpoint
Faults detection functions:
• Reports alarms for input under/overvoltage
protection
• Reports alarms for output under/overvoltage
• Reports alarms for fan faults
• Reports alarms for under/overtemperature
• Reports alarms for output overcurrent, and short
circuits
Appendix B describe the FRU data to be stored in power supply EEPROM by vendor. For more information,
please refer to PMBus_Specification_Part_I_Rev_1-2, PMBus_Specification_Part_II_Rev_1-2, Appendix A.
Safety Precautions
You are advised to provide two power inputs for the system. Power configuration in N+N mode is preferred.
The following figure shows the power configuration in 3+3 mode.
• Configure a circuit breaker (with a rated current not less than 16 A) for each PSU.
• The rated current of the upstream circuit breaker for each power input is recommended to be not less
than 50 A.
• The PSU should be properly grounded. Otherwise, it will be damaged due to a lightning strike.
