ESCRIPTION
The YR40.245 is a redundancy module, which can be
used to build redundant systems. The module has one
input and one output and can carry nominal currents up
to 40A. The output is equipped with a plug-connector,
which allows replacing the power supply or the
redundancy module while the system is running (hot-
swapping)
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.
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. The large international approval package
makes this unit suitable for nearly every application.
