Note: For dynamic condition +12V min loading is 1A.
3.3.5
Capacitive Loading
The power supply must be stable and meet all requirements, with the following capacitive
loading conditions.
3.3.6
Ripple/Noise
The maximum allowed ripple/noise output of the power supply is defined in below table. This is
measured over a bandwidth of 10Hz to 20MHz at the power supply output connectors. A 10µF
tantalum capacitor in parallel with a 0.1µF ceramic capacitor is placed at the point
of measurement.
3.3.7
Grounding
The output ground of the pins of the power supply provides the output power return path. The
output connector ground pins shall be connected to the safety ground (power supply enclosure).
This grounding should be well designed to ensure passing the max allowed Common Mode
Noise levels.
The power supply shall be provided with a reliable protective earth ground. All secondary
circuits shall be connected to protective earth ground. Resistance of the ground returns to
chassis shall not exceed 1.0 mΩ. This path may be used to carry DC current.
