2.1.4.5 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.

Note:
For dynamic condition +12V min loading is 1A.
2.1.4.6 Capacitive Loading
The power supply is stable and meets all requirements with the following capacitive loading
ranges.

2.1.4.7 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.
2.1.4.8 Residual Voltage Immunity in Standby mode
The power supply is immune to any residual voltage placed on its outputs (Typically a leakage
voltage through the system from standby output) up to 500mV. There is neither additional heat
generated, nor stressing of any internal components with this voltage applied to any individual
or all outputs simultaneously. It also does not trip the protection circuits during turn on.
