Description
The 1606-XLSRED40 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. The module is suitable for power
supplies with constant current overload behavior as well
as any kind of “Hiccup” overload behavior.
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 36mm 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.
