Redundant operation
Redundant circuits are suitable for the supply of systems
which make especially high requirements on the operational
safety. If a fault occurs in the primary circuit of the first power
supply unit, the second device automatically takes over the
entire power supply, without interruption, and vice versa. For
this reason, the power supply units to be connected in parallel
are dimensioned in such a way that the total current
requirement of all consumers can be completely covered by
one power supply unit. 100% redundancy makes external
decoupling diodes necessary (QUINT-DIODE/40, Order No.
2938963)!

Increased performance
For n parallel connected devices, the output current can be
increased to n x I
N
. Parallel connection to increase efficiency
is used for the expansion of existing systems. It is advisable
to use parallel connection if the power supply unit does not
cover the current requirement of the most powerful
consumer. Otherwise the consumers should be spread
among individual devices independent of one another. A
maximum of five devices can be connected in parallel!
