Overview of Auto Change Over Panel (ATS)

Reliable Automatic Power Transfer for Uninterrupted Operations

An Auto Change Over Panel, also known as an ATS (Automatic Transfer Switch) Panel, is a critical electrical system designed to ensure continuous power supply during mains power failure. The panel automatically transfers the electrical load from the utility supply to a standby generator and restores it back to mains once power is available.

AAVAD Instrument Pvt. Ltd. manufactures robust and intelligent Auto Change Over Panels that provide seamless power transfer, enhanced safety, and reliable performance for residential, commercial, and industrial applications.

How ATS (Auto Change Over Panel) Works

The ATS panel continuously monitors the incoming AC mains supply. When a power failure or voltage abnormality is detected:

1. The ATS commands the generator set to start automatically

2. Once the generator stabilizes, the load is transferred to standby power

3. During mains restoration, the ATS switches the load back to utility power

4. The generator is then stopped after a programmed cooling period

This fully automatic operation ensures zero or minimal downtime, making ATS panels essential for hospitals, data centers, fire safety systems, and critical infrastructure.

Dual Mains Auto Change Over for Fire Safety Compliance

AAVAD also manufactures Dual Mains Automatic Change Over Panels designed to meet fire safety and building regulations. These panels are widely used in buildings with duplicate power supplies and automatically switch between sources during fire or mains failure to ensure continuous power to firefighting lifts and safety systems.
