Redundant module 40 A Dimension Series

24-56 V DC, 2x20 A

  • For N+1 and 1+1 Redundant Systems
  • MOSFET transistors
  • Minimum power loss

Product description

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.
