8Load Connections in Local Sensing Mode | Xantrex Technology XG 850

Using Multiple Power Supplies

Connecting to the Load in Local Sensing Mode (Parallel Control Method)

Connect the power supplies in parallel to obtain a single output supply with a higher output current set point. Set all of the outputs to the same voltage before connecting the positive (+) and negative (–) terminals in parallel. The total current available is the sum of the maximum currents of each power supply.
