Standby Output

The 5VSB output is present when an AC input greater than the power supply turn on voltage is
applied.
12.1.3.1 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.
These shall be measured at the output connectors.

12.1.3.2 Dynamic Loading
The output voltages remain within limits specified for the step loading and capacitive loading
specified in the table below. The load transient repetition rate is tested between 50Hz and 5kHz
at duty cycles ranging from 10%-90%. The load transient repetition rate is only a test
specification. The  step load may occur anywhere within the MIN load to the MAX
load conditions.

Notes:
1. Step loads on each 12V output may happen simultaneously.
2. The +12V should be tested with 2200F evenly split between the four +12V rails
3. This will be tested over the range of load conditions in section 12.1.2.
12.1.3.3 Capacitive Loading
The power supply is stable and meets all requirements with the following capacitive loading
ranges.
