INTERFACE
Using the redundancy module, it is possible for two power
supply units of the same type that are connected in parallel on
the output side to increase performance or for redundancy to
be isolated from one another..
The reliability of a power supply determines the availability of
individual components in a system and whether complex sys-
tems can function safely.
Redundant circuits are intended to supply systems that set
high demands on operational reliability. Long-term, perma-
nent system availability is ensured by the redundant setup of
the power supply.
The power supply of a system can be configured redundantly
by switching at least two power supply units in parallel.
Together, they then supply the connected devices.
The power supply units involved must be dimensioned to en-
able the total current requirements of all loads to be covered
by one single power supply unit. In the event of an internal de-
vice fault or failure of the mains power supply on the primary
side, the other device automatically takes over the entire
power supply of the loads without interruption.
If the devices connected upstream are QUINT POWER
power supply units, redundance can also be monitored via
series connection of the DC-OK relay contacts.
This means that operational reliability of the entire system can
be effectively increased.
Features
– Decoupling power supply units switched in parallel
– Installation in potentially explosive areas is permitted
– Load currents up to 60A are possible
– Easy installation by snapping onto the DIN rail
Make sure you always use the latest documentation.
