GENERAL DESCRIPTION

SHORT-FORM DATA

The YR80.242 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 40A output
current and one output, which can carry nominal
currents up to 80A. In addition to the YR80.242, the
YR80.241 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.

Input voltage
DC 12-28V
Input voltage range 8.4-36.4Vdc
Input current
2x 0-40A
2x 40-65A
Output current
0-80A
80-130A
max. 44A

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.
