Redundant module 40 A Dimension Series

  • N+1 ja 1+1 varmennukseen
  • MOSFET transistors
  • Minimum power loss
  • Hot-Swap connectors

Product description

The YR40.245 is a redundancy module, which can be used to build redundant systems. The module has one

input and one output and can carry nominal currents up to 40A. The output is equipped with a plug-connector, which allows replacing the power supply or the redundancy module while the system is running (hotswapping).


The novelty of this redundancy module is the utilization of mosfets instead of diodes for the decoupling of the output. 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.
