This device is an industrial-grade Automatic Transfer Switch (ATS), designed to automatically transfer electrical loads between two power sources — typically the main utility supply and a backup generator — ensuring continuous power in case of utility failure. The ATS monitors voltage and frequency and switches to the alternate source within seconds when it detects an outage or abnormal conditions.
