2.2.3.2 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.
A reliable protective earth ground is provided on the power supply. All secondary circuits are
connected to protective earth ground. Resistance of the ground returns to chassis does not
exceed 1.0 mΩ. This path may be used to carry DC current.
2.2.3.3 Remote Sense
No remote sense and remote sense return signal is required on this power supply. The power
supply operates within specification over the full range of voltages at the power supply’s output
connector.
2.2.3.4 Output Power / Currents
The following table defines power and current ratings for the 600-W continuous power supply in
a 1+0 or 1+1 redundant configuration. The combined output power of both outputs does not
exceed the rated output power. The power supply meets both static and dynamic voltage
regulation requirements for the minimum loading conditions. Also, the power supply supplies the
listed peak currents and power for a minimum of 10 seconds. Outputs are not required to be
peak loaded simultaneously.

2.2.3.5 Standby Output
The 5VSB output is present when an AC input greater than the power supply turn-on voltage is
applied.
2.2.3.6 Voltage Regulation
The power supply output voltages stay within the following voltage limits when operating at
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise
specified in the Voltage Regulation Limits table. All outputs are measured with reference to the
GND. The +12V and +5VSB outputs are measured at the power distribution board output
harness connector.
