Diesel generators with an Automatic Transfer Switch (ATS) provide automatic backup power transfer when the utility supply fails and returns.
An ATS-equipped generator system combines a diesel generator with an automatic transfer switch and compatible control equipment. When a utility power failure is detected, the system can start the generator and transfer the designated load once acceptable generator power is available. When utility power is restored and stable, the system transfers the load back according to its configured sequence.
