An automatic changeover switch (ATS) is an electrical device that automatically transfers the power supply from the main source (utility power) to a backup source (such as a generator or inverter) when it detects a power failure, and switches back to the main supply once power is restored.
Description:
The automatic changeover ensures continuous power supply without manual intervention. It monitors both power sources and instantly switches to the alternate one when needed, preventing downtime or damage to electrical equipment.
