FPS-T1U Instruction Manual

CHAPTER 20 PARALLEL AND SERIES OPERATION

20.1 Parallel operation

Up to 3 x FPS-T1U racks with up to 8 x FPS1000 installed units of the same output voltage rating can be connected in parallel. The built-in Oring diodes on the main output and on the +12V auxiliary voltage in each FPS1000 unit allow N+1 operation. By connecting the CS signal between the paralleled units, automatic current balance is achieved, with +/-10% accuracy. For input voltages less than 100Vac, maximum output Power derated by 10% of the Power rating. Refer to Fig 20-1 for output Power derating in parallel operation.
