The YR40.242 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. Besides the YR40.242, the YR40.241 is also available. This unit has an additional circuit included, which generates a supply voltage for the internal MOSFETS even when the output of the unit is in a short circuit condition. This makes the unit suitable for any power supplies. 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 36mm width on the DIN-rail. Large connection terminals allow a safe and fast installation. The large international approval package makes this unit suitable for nearly every application.
