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 YRM2.DIODE 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 10A output current and 1 output which can carry nominal currents up to 20A. The module is suitable for power supplies with constant current overload behaviour as well as any kind of Hiccup overload behaviour. The YRM2.DIODE has a monitoring circuit included and is the perfect solution when the power supply has no DC-OK function. 2 LEDs and 2 relay contacts signal when 1 of the 2 DC-input voltages is not in range due to a non-functioning or disconnected power supply. In addition to the YRM2.DIODE is the YR2.DIODE which has no monitoring circuitry included. This is the perfect fit when the power supply itself is already equipped with a DC-OK signal (e.g.; DIMENSION Q-Series). Large screw terminals allow an easy installation and a huge international approval package for a variety of applications makes this unit suitable for nearly every situation.
