2.2.4.11 Grounding
The ground of the pins of the power supply output connector provides the power return path.
The output connector ground pins are connected to safety ground (power supply enclosure).
This grounding is well designed to ensure passing the maximum allowed Common Mode Noise
levels.
The power supply must be provided with a reliable protective earth ground. All secondary
circuits are 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.
2.2.4.12 Remote Sense
The power supply has remote sense return (ReturnS) to regulate out ground drops for all output
voltages: +3.3V, +5V, +12V1, +12V2, -12V, and 5VSB. The power supply uses remote sense to
regulate out drops in the system for the +3.3V, +5V, and 12V1 outputs. The remote sense input
impedance to the power supply is greater than 200
resistor connecting the remote sense to the output voltage internal to the power supply. Remote
sense must be able to regulate out a minimum of 200mV drop on the +3.3V output. The remote
sense return (ReturnS) must be able to regulate out a minimum of 200mV drop in the power
