4.4.14 Series Operation
1. GENERAL: Two power supplies of the same rating can be connected in series to increase the
2. Series connection for increased output voltage:
current limits of each power supply to the maximum that the load can handle without damage. It is
recommended to connect diodes in parallel to each unit output to prevent reverse voltage during start-
up condition or in case one of the units shuts down. Each diode should be rated to at least the power
supply’s output current. Refer to Fig: 4-12 and 4-13 for this operating mode.

When two power supplies are connected in series, they should be programmed to the same output
