Forced Load Sharing
The +12V output shall have forced load sharing. The +12V output load shall be shared between
parallel units within 10% (+5%, -5%) from the half load point to full load for a single supply. For
purpose of verifying current sharing function, full load value shall be 33A for a single supply for
the +12V output. The supplies must be able to load share with up to 2 power supplies in parallel
and operate in a hot swap/redundant 1+1 configuration. The 5VSB output is not required to
share current between power supplies however these outputs are connected together in the
system and a failure or hot swap of a redundant power supply will not cause these outputs to go
out of regulation in the system.
Examples of load share accuracy at limits of acceptability (+5%, -5% sharing):
2 power supplies and system load equals 33A: PS #1 = 17.325A, PS #2 = 15.675A

Load Sharing, Load Monitoring Signal Characteristic
The load share signal provides both the load sharing function and +12V output current
information. The characteristics of the load share signal are defined below in the table below.

Control And Indicator Functions
Signals that can be defined as low true or high true shall adopt the following conversion: signal#

3.4.1
PSON#(Power supply enable)
The PSON
#
signal is required to remotely turn on/off the power supply. PSON
#
is an active low
signal that turns on the +12V power rail. When this signal is not pulled low by the system, or left
open, the +12V output is turned off. This signal is pulled to a standby voltage by a pull-up
resistor internal to the power supply. Refer to Figure 3.6 Turn On/Off Timing diagram. When in
off or standby condition, the +12V output shall be less than 50mV with respect to output return.
