Protective circuit for the parallel connection of more than two power supplies
For connection of more than two power supplies in parallel, additional measures must be
taken to prevent high backward feeding currents in the event of a secondary device fault.
For this purpose, a suitable protective circuit (e.g. decoupling diode or DC-conform circuit-
breaker) must be installed between each "+" terminal of the power supply and the common
connection point.
