The YR40.482 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 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.
