Σ = I

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 paral-

lel are dimensioned in such a way that the total current re-

quirement 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)!

Σ = 2 x I

Increased performance

For n parallel connected devices, the output current can be

increased to n x I

. 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 con-

sumer. Otherwise the consumers should be spread among

individual devices independent of one another. A maximum

of five devices can be connected in parallel!
