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.
