2.4.2.3 Grounding
The ground of the pins of the PDB output connectors provides the power return path. The output
connector ground pins is connected to safety ground (PDB enclosure). This grounding is well
designed to ensure passing the maximum allowed Common Mode Noise levels.
2.4.2.4 Remote Sense
The following table lists the remote sense requirements and connection points for all the
converters on the PDB and the main 12V output of the power supply.
