The YR20.242 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 24A output current and one output, which can carry nominal currents up to 24A. In addition to the YR20.242, the YR20.246 is available which is featured with an automated load sharing between the connected power supplies and functions which monitor defects in the redundancy circuit or too high output currents, which could prevent redundancy, if one power supply fails.
For N+1 and 1+1 Redundant Systems Dual Input with Single Output Only 60mV Voltage Drop at 10A Output Current Only 0.6W Loss at 10A 160% (32.5A) Peak Load Capability Reverse Input Polarity Protection Full Power Between -40°C and +70°C Width only 32mm Rugged Metal Housing Easy Wiring: Distribution Terminal for Negative Pole Included
