Mains to DG Automatic transfer switch panels are used where the primary mains supply is backed up by a secondary supply forwarded to load. This type of panel is used for critical loads, such as emergency hospital, fire fighting, lifts common area load.
The ATS panel monitors the mains supply and will transfer the load to the secondary supply if it should fail, or fall outside preset limits.
An adjustable delay is included when switching from primary to the secondary supply. A switch is included to allow manual switching between the primary and secondary supplies.
