ATS-4S

Automatic transformer switch-4 display

An Automatic Transfer Switch (ATS) is an electrical device that automatically transfers the power supply for connected loads from a primary source (typically the utility grid) to a backup or alternate source (like a generator or a second utility feed) when it detects a failure, outage, or significant quality issue (e.g., undervoltage, overcurrent) in the primary source.
