Signals that can be defined as low true or high true use the following convention:
Signal# = low true
Reserved pins are reserved for future use.
2.3.3.2 Grounding
The ground of the pins of the power supply output connector provide the power return path. The
output connector ground pins are connected to safety ground (power supply enclosure).
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 do not
exceed 1.0 m . This path may be used to carry DC current.
2.3.3.3 Remote Sense
No remote sense and remote sense return signal is required on the 650-W power supply.
2.3.3.4 Output Power/Currents
The following table defines power and current ratings for the 650-W continuous (720-W pk)
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.
