13.3.4.2 Standby Output
The 12VSB output is present when an AC input greater than the power supply turn on voltage is
applied.
13.3.4.3 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.

13.3.4.4 Dynamic Loading
The output voltages remains 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.

13.3.4.6 Grounding
The output ground of the pins of the power supply provides the output power return path. The
output connector ground pins are connected to the safety ground (power supply enclosure).
This grounding is well designed to ensure passing the max allowed Common Mode Noise levels.
The power supply is provided with a reliable protective earth ground. All secondary circuits is
connected to protective earth ground. Resistance of the ground returns to chassis does not
exceed 1.0 m. This path may be used to carry DC current.
