Starpoint Parallel Circuit connection.
Starpoint parallel circuit connection is achieved by "daisy chaining" all the parallel pins together in any group of
modules required to share.

All the PIN 5 and PIN 7 perform the same function and are linked internally in the module.
Functionally, the shared parallel connection forces each module of a pair to drive approximately the same current.
Whichever module is driving the least current has it's voltage increased slightly to balance it. The load current is
shared evenly amongst the modules. This improves the reliability by ensuring that no one module takes more stress
than any others in a sharing group.
Sharing can take place from module to module within the same power supply or between modules configured in
different power supplies.
