Redundant circuits are suitable for supplying systems, which
place particularly high demands on operational safety. If a
fault occurs in the primary circuit of the first power supply unit,
the second device automatically takes over the complete

power supply without interruption, and vice versa. For this
purpose, the power supply units to be connected in parallel
must be large enough that the total current requirements of all
loads can be fully met by one power supply unit. External
decoupling diodes are required for 100% redundancy (TRIO-

For n parallel connected devices, the output current can be
increased to n x I N . Parallel connection for increasing power
is used when extending existing systems. A parallel

Otherwise, the load should be divided between individual
devices that are independent from one another.
