2.3.3.5 Standby Output
The 5VSB output is present when an AC input greater than the power supply turn-on voltage is
applied.
2.3.3.6 Voltage Regulation
The power supply output voltages stay within the following voltage limits when operating at
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise
specified in Table 61. All outputs are measured with reference to the GND. The +12V and
+5VSB outputs are measured at the power distribution board output harness connector.

+ 5VSB
2.3.3.7 Dynamic Loading
The output voltages remain within limits specified for the step loading and capacitive loading
presented in the following table. The load transient repetition rate has been tested between 5
Hz and 5 kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only a
test specification. The
defined in the following table.
Output
12V
+5VSB
Notes:
1. Step loads on each 12V output may happen simultaneously.
2. The +12V should be tested with 2200 F evenly split between the three +12V rails.
