1570W Power Supply
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.
Output Level
+12V
+3.3V standby
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.)
Level
Output Level
1,2,3
+3.3V standby
+12V
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.
