SAM825-AMF

SAM825-AMF controllers are high-performance, complete, automatic, and configurable instruments, useful for controlling generator sets in emergency automatic mains failure (AMF) installations.

SAM825-AMF controllers automatically start and stop generator sets, protect them by means of the connected and controller-generated alarms, and visualize the most relevant values. They carry out the general coordination of the operation and the switching of the consumers from the Mains to Generator and vice versa.
