Local Operation
Using Multiple Supplies
Release 2.1 67
Sensing for Parallel Operation Use default local sensing to enhance power
sharing between units, as the impedance of the load lines will tend to correct for
current imbalance. If you use remote sensing at the load for better voltage regulation,
one supply always operates in current limit mode and supplies most of the power.

Operation
Split supply operation uses two power supplies to obtain two positive voltages with
a common ground, or to obtain a positive-negative supply.
