ApplicationThe primary switch mode power supply CP‑S 24/5.0 has two voltage inputs. This enables the supply with AC or DC. Furthermore the CP‑S 24/5.0 is equipped with two generous capacitors, which ensure mains buffering of
at least 100 ms. That is why the devices can be used worldwide also in high fluctuat‑networks and battery‑powered plants.
Due to their reliable construction, the devices can be used in very harsh industrial environments.
The power reserve of up to 50 % enables trouble‑free starting of heavy loads, so that no oversized
power supply is needed.

Operating mode
Parallel operation
In order to enable redundancy, up to 5 devices can be connected in parallel. For a symmetric distribution
it is advisable to execute the line connections with the same cross sections and same lengths.
Parallel operation, redundancy - without CP-A RU
Redundant circuits are suitable to increase the operational reliability in case of errors. If a fault occurs in
the first power supply circuit (called initial fault), the power supply of all consumers will be taken over by
the second, redundant supply circuit. For this reason the power supply units to be connected in paral‑
lel are dimensioned in such a way that the total current requirement of all consumers can be completely
covered by one power supply unit.
Extended function with accessories
Parallel operation, true redundancy with decoupling provided by the CP-A RU
Redundant circuits are used to increase the operational reliability and eliminate power supply outages.
Events that can cause a power supply failure include: incorrect wiring, blown fuses or failure of a single
power supply. If a fault event occurs (called initial fault) in the first power supply circuit, power to all loads
is then supplied by the second (redundant) power supply. For this reason, both power supplies must be
sized to handle the total current requirement of all loads. The primary and the redundant power supplies
are decoupled from one another by the CP‑A RU unit.
It automatically switches from the primary to the redundant supply after a fault. It decouples the output
of the failed power supply from the redundant supply preventing the initial fault from shorting or compro‑
mising the redundant supplies’ output. In this way, uninterrupted supply of power to all loads is guaran‑
teed.When available, the two power supplies should be connected to different input voltage phases, to avoid oss of power caused by a blown fuse on
the primary side of the power supplies.
