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.

Note You do not need to use remote sensing for series operation. If you choose to use
it, refer to
