Xantrex Technology XPD 33-16 Configuring Multiple Supplies for Series Operation Voltage Mode Only

Using Multiple Supplies

Configuring Multiple Supplies for Series Operation (Voltage Mode Only)

Connect power supplies in series to obtain a single output supply with higher output voltage. Connect the negative (–) terminal of one supply to the positive (+) terminal of the next supply. The total voltage available is the sum of the maximum voltages of each supply (add voltmeter readings). The maximum current available to the load is equal to the current of the lowest rated supply in the series. See Figure 3.2 for a representation of series operation.
