10.2.2 Output Current Rating
The combined continuous output power for all outputs will not exceed 1570W. Each output has
a maximum and minimum current rating shown in Table 23.

+12V 0A 130.8A 144.0A
+3.3V standby 0.1A 6.0A
Note: 1. Values are at the system level. For 1+1 redundant systems, the load each power supply will provide will
be based on its current sharing accuracy.
10.2.3 Over- and Under-Voltage Protection
The power supply will provide latch mode over and under voltage protection as defined in the
following table. A fault on any output will cause the rest of the outputs to latch off. (In addition,
see note 3 in the following table.)
Table 24. Over- and Under-Voltage Limits
Level Under-Voltage Over Voltage
Output Level Minimum Maximum Minimum Maximum
+3.3V standby

2.77V 3.00V 3.76V 4.3V
+12V 10.5 11.0 13.5 15.0
Notes:
1. In standby mode, the power supply will not latch off due to an under-voltage condition.
2. In standby mode, the power supply may or may not latch off due to an over-voltage condition.
3. A fault on any output other than +3.3V standby will not cause the +3.3V standby to turn off. A fault on +3.3V
standby will cause the other outputs to turn off.
