Operation
Use series operation to obtain a single higher voltage output using two or more
supplies. Connect the negative (–) output terminal of one supply to the positive (+)
output terminal of the next supply. See Figure 3.2. The total voltage available is the
sum of the maximum voltages of each supply (add voltmeter readings, to a maximum
of 600 V). The maximum allowable current for a series string of power supplies is
the output current of a single supply in the string.

CAUTION
The maximum allowable sum of the output voltages is 600 Vdc.
