SAM825k controllers are high-performance, complete, automatic, and configurable instruments, useful for controlling generator sets in installations with no electric mains available.
SAM825k controllers automatically start and stop generator sets, protect them by means of the connected and controller-generated alarms, and visualize the most relevant values.
