Parallel connection for redundancy
Redundant circuits are suitable for supplying systems, which
place particularly high demands on operational safety.
In order to set up a redundant power supply solution, two UPS
systems of the same type (consisting of a power supply unit,
DC-PS, redundant 1 ? .... ? n) are connected in parallel and de-
coupled. No further adjustments to the default setting are nec-
essary.

Parallel connection for redundancy
If a fault occurs in the first UPS system, the second UPS sys-
tem automatically takes over the entire supply without inter-
ruption and vice versa. For this purpose, the UPS systems to
be connected in parallel are dimensioned so that the total cur-
rent requirements of all loads can be fully met by one UPS
system.
