13.1.4 Remote On/Off control at parallel operation

The paralleled racks can be turned On or Off via a single On/Off control. Refer to Fig 13-5 for typical application. The Signal Return function of all the paralleled racks should be connected together to create a common Signal Return bus. The Signal Return bus may be connected to the -V or the +V potential or floated. In any case do not connect the Signal Return bus to different potentials.

13.2 Series operation

Two FPS-S1U racks 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 13-6 and 13-7 for a typical series connection of power supplies.

CAUTION

Series operation is not applicable for units with I2C bus option.
