10.3.2.3 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.
10.3.2.4 Remote Sense
Below is listed the remote sense requirements and connection points for all the converters on
the PDB and the main 12V output of the power supply.
