Xantrex Technology XFR 2800 manual Supplies for Split Supply Operation

Local Operation

Using Multiple Supplies

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.

(Local sense lines shown are default J10 connections.)

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