2.4.8.3 Grounding
The output ground of the pins of the power supply provides the power return path. The output
connector ground pins are connected to safety ground (power supply enclosure). This
grounding is designed to ensure passing the maximum allowed common mode noise levels.
2.4.8.4 Standby Output
The 5VSB output is present when an AC input greater than the power supply turn-on voltage is
applied.
2.4.8.5 Remote Sense
The power supply has remote sense return (ReturnS) to regulate out ground drops for all output
voltages: +3.3V, +5V, +12V1, +12V2, +12V3, +12V4, +12V5, -12V, and 5VSB. The power
supply uses remote sense to regulate out drops in the system for the +3.3V outputs. The +5V,
+12V1, –12V and 5VSB outputs only use remote sense referenced to the ReturnS signal. The
remote sense input impedance to the power supply is greater than 200Ω on 3.3V, 5VS. This is
the value of the resistor connecting the remote sense to the output voltage internal to the power
supply. Remote sense is able to regulate out a minimum of a 200mV drop on the 3.3 output.
The remote sense return (ReturnS) is able to regulate out a minimum of a 200mV drop in the
power ground return. The current in any remote sense line is less than 5mA to prevent voltage
