Description

Automatic Transfer Switch (ATS) and Manual Transfer Switch (MTS) are devices used to shift power between the utility and a backup power source. ATS operates automatically during power outages, ensuring uninterrupted supply, while MTS requires manual operation to switch sources, offering a cost-effective solution for controlled power transfer.
