Lovato ATL800 Automatic Transfer Switch

 

Lovato ATL800 Automatic Transfer Switch for 2 Supply Lines.

The automatic transfer switch controller ATL800 is used for the automatic or manual switching of the load between two 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 a third control device as tie breaker or non-priority load management. the layout and system status are displayed directly on the graphic LCD.

The Lovato ATL800 is available with a range of expansion modules and accessories; click here to view all available Lovato expansion modules and accessories.
