GENERAL DESCRIPTION

SHORT-FORM DATA

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 power supplies with up to 40A output
current and one output, which can carry nominal
currents up to 80A. The module is suitable for power
supplies with constant current overload behavior as well
as any kind of “Hiccup” overload behavior. In addition
to the YR80.241, the YR80.242 is also available which is
cost-optimized and suitable for all DIMENSION power
supplies except the QT40 series.

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.
