ENERAL

ESCRIPTION

The YR80.241 is a redundancy module, which can be
used to build 1+1 and N+1 redundant systems. It is
equipped with two input channels which can be
connected to 40A power supplies and one output which
can carry nominal currents up to 80A.

The novelty of this redundancy module is the utilization
of mosfets instead of diodes for the decoupling of the
two input channels. This reduces the heat generation
and the voltage drop between input and output. The
redundancy module does not require an additional
auxiliary voltage and is self-sufficient even in case of a
short circuit across the output.

Due to the low power losses, the unit is very slender and
only requires 46mm width on the DIN-rail. Large
connection terminals allow for a safe and fast
installation with a large international approval package.
This unit is suitable for nearly every application.
