8.2.4
The grounds of the pins of the power supply output connector provide the power return path.
The output connector ground pins shall be connected to safety ground (power supply
enclosure). This grounding should be well designed to ensure passing the maximum
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.
8.2.5
The 5 VSB output shall be present when an AC input greater than the power supply turn on
voltage is applied.
8.2.6
The power supply has remote sense return (ReturnS) to regulate out ground drops for all output
voltages: +3.3 V, +5 V, +12 V1, +12 V2, +12 V3, -12 V, and 5 VSB. The power supply uses
remote sense (3.3 VS) to regulate out drops in the system for the +3.3 V output. The +5 V, +12
V1, +12 V2, +12 V3, –12 V and 5 VSB outputs only use remote sense referenced to the
ReturnS signal.
The remote sense input impedance to the power supply must be greater than 200 Ω on 3.3 VS
and 5 VS; this is the value of the 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 a
200 mV drop on the +3.3 V output.
The remote sense return (ReturnS) must be able to regulate out a minimum of a 200 mV drop in
the power ground return. The current in any remote sense line shall be less than 5 mA to
prevent voltage sensing errors. The power supply must operate within specification over the full
range of voltage drops from the power supply’s output connector to the remote sense points.
8.2.7
The power supply output voltages must stay within the following voltage limits when operating at
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise.
