WIRING DIAGRAM FOR OUTPUT
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 B5 or D4) must be connected on all sharing modules. It is not required that the SENSE signals are con-
nected 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. The VSB (Standby Output) output of the power module can also be connected in parallel; internal output isolation devices are provided 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.
