20.2 Series operation
Up to three FPS1000 with the same output voltage rating can be connected in series 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 20-3 for a typical series connection of power supplies.
