+12VRS (Main Output Remote Sense)
Dotted lines show optional remote sense connections.
Optional remote sense lines can be attached to a load that is a distance
away from the power supply to improve regulation at the load.

CURRENT SHARING NOTES
1. Main 12VDC Output: Analogue active share bus. The ISHARE bus (Pin B3) must be connected on all sharing modules. It is not required that the SENSE signals are connected to the remote load for current share
to operate correctly.
2. Up to eight (8) power modules can be connected in parallel (non-redundant) or N+1 configuration. The current share bus is analogue bi-directional (can source or sink current from the ISHARE bus). The voltage
of the bus would measure 8VDC for a single power module at 100% load; for two (2) modules sharing a common load the ISHARE bus voltage would be 4V for a perfect 50/50 current share scenario.
3. VSTANDBY output power modules can also be connected in parallel and have internal output isolation devices; however the combined available power is limited to that available from a single power module
(3.3V or 5V; 20W) irrespective of the number of modules connected in parallel.
