GENERAL DESCRIPTION
The YR40.242 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 power supplies with up to 20A output
current and one output, which can carry nominal
currents up to 40A. In addition to the YR40.242, the
YR40.241 is also available. This unit has an additional
circuit included, which generates a supply voltage for
the internal mosfets even when the output of the unit is
in a short circuit condition. This makes the unit suitable
for any power supplies.
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 36mm 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.
