Parallel Operation

1) Adjust each power supply to the exact same output voltage with same

load and cooling conditions.

2) Use the same wire length for each power supply (star connection) and

energize all units at the same time to avoid triggering overload protection.

3) To prevent high reverse currents in the event of a secondary output

fault, it is recommended to install a protective circuit at the output of each

device when more than two power supplies are connected in parallel

(e.g. decoupling diode or DC fuse).

For n parallel connected devices, the output current can be increased

to 90% of n x I

Phase redundancy

1) If any single phase fails, operation is still guaranteed.

Load:

90% of n x I
