Configuring Multiple Supplies for Series Operation

A maximum of two power supplies of the same rating can be connected in
series to increase the output voltage.
CAUTION: Equipment damage
When two power supplies are connected in series, they should be programmed to
the same output voltage to prevent damage to the lower voltage supply at short
circuit condition.
Connecting to the Load in Local Sensing Mode
Connect the negative (–) output terminal of one power supply to the
positive (+) output terminal of the next power supply. See Figure 3-6 for a
representation of series operation.
