6.2 Series operation
Two units can be seriesly connected to increase the output voltage or to create a bipolar voltage source. It is recommended to connect diodes in parallel with each output to prevent reverse voltage in case of failure in one of the power supplies. Each diode should be rated to at least the power supply rated output voltage and output current. Refer to Fig
Series connection for increased output voltage.
