Series / parallel operation -- 1+1 Redundancy Use of 2 identical power supplies in parallel to provide continued operation following most failures in a single power supply. The 2 power supply outputs should be isolated from each other by utilizing diodes or other switching arrangements. N+1 Redundancy Use of 3 or more identical power supplies in parallel to provide continued operation following most failures in a single power supply. All power supply outputs should be isolated from each other by utilizing diodes or other switching arrangements.

The YR80.242 is a redundancy module which can be used to build 1+1 and N+1 redundant systems. It is equipped with 2 input channels which can be connected to power supplies with up to 40A output current and 1 output which can carry nominal currents up to 80A. In addition to the YR80.242 the YR80.241 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 2 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.
