Alpha Drives has just completed an Automatic Generator switch over panel with Dual motorised operators for auto switch over. Combining surge protection , cct breakers and a CT Metering Chamber for ESB the onboard Siemens ATC3100 controller provides continuous power in the event of a supply failure switching between two independent power sources.

With adjustable set limit values and delay times it quickly switches to the back up Generator supply ensuring at same time that the the secondary supply has the required power quality . The exact conditions and timing required in either the main and secondary power supplies can be defined within the ATC unit.
