3.8 Load sharing
3.8.1. Forced Load Sharing
The +3.3V, +5V and +12V outputs shall have forced load sharing. The corresponding output
shall share within 5% at full load when operated in a redundant 1+1 configuration. The 5VSB
and –12V outputs shall not have forced load sharing between power modules.
Example of load share accuracy:
Power supply #1 = 20A
Power supply #2 > 19A and < 21A
3.8.2. Load Sharing Signal
The power supplies load share shall use a single load share bus signal connected between
each corresponding output. If the load sharing is disabled by shorting the bus to ground, the
power system shall continue to operate within regulation limits for loads less than or equal to
the full load rating of each power supply. The failure of one power supply shall not effect the
output voltages of the other supply still operating.
