The automatic transfer switch controller ATL900 is used for the automatic or manual switching of the load between three lines in accordance with the selected switching logic. It has outputs for the “automatic” and/or “manual” control of contactors or motorised circuit breakers and switches. It can also manage two more control devices as tie breakers or non-priority load management. It has four current inputs for managing switching with power thresholds. The layout and system status are displayed directly on the graphic LCD.
