5.3.3.3 Grounding
The ground of the pins of the PDB output connectors provides the power return path. The output
connector ground pins shall be connected to safety ground (PDB enclosure).
5.3.3.4 Remote Sense
The PDB has remote sense return (ReturnS) to regulate out ground drops for all output voltages;
+3.3V, +5V, +12V1, +12V2, +12V3, 12V4, -12V, and 5VSB. The PDB uses remote sense
(3.3VS) to regulate out drops in the system for the +3.3V output. The +5V, +12V1, +12V2,
+12V3, 12V4, –12V, and 5VSB outputs only use remote sense referenced to the ReturnS signal.
5.3.3.5 +12 V Outputs Loading
This describes the +12V outputs loading from the power distribution board with a single or two
ERP700W power supply plugged into the input of the power distribution board.

Note:
1. The peak current shall be supplied for a minimum duration of 12 seconds.
2. The combined continuous total power limit for all outputs is 725-W maximum.
5.3.3.6 DC/DC Converters Loading
The following table defines the power and current ratings of the three DC/DC converters located
on the power distribution board, each powered from the +12 V rail. The three converters must
meet both static and dynamic voltage regulation requirements for the minimum and maximum
loading conditions.

3.3x24=79.2 W 5x30=150 W 0.5x12=6 W
Note:
1. The straight sum of the three maximum powers = 235.2 W, but considering the 3.3/5 V power limit, it may be 176-W
maximum combined power.
