The YR40.241 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. In addition to the YR40.241, the YRH40.241 is also available which is cost-optimized and only suitable for power supplies with a HiccupPLUS 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.
