Using Multiple Power Supplies

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 3 representation of series operation.
