Lovato RGK Parallel Automatic Mains Failure Gen-Set Controllers

 

Lovato RGK Parallel Automatic Mains Failure Gen-Set Controllers for Industrial Engine, Generator and ATS Control Applications

The Lovato RGK Parallel Automatic mains failure gen-set controllers are capable of automatically switching to a generator power source and starting the generator in the event of a failure in the electrical mains. The RGK series of gen-set transfer switches are also able to supervise the operation of contactors as well as motorised circuit breakers and changeover switches in open transition. In addition, it has programmable inputs, outputs and alarms, and is also compatible with Lovato Synergy software which enables remote control and supervision of the unit.
