What is an Auto Change Over Panel (ATS Panel)?

Automatic Power Transfer for Uninterrupted Electrical Supply

An Auto Change Over Panel, also known as an ATS (Automatic Transfer Switch) Panel, is an electrical control panel designed to automatically transfer the electrical load between two power sources, typically utility mains and a standby generator. It ensures uninterrupted power supply during mains failure and restores power back to the utility supply once it becomes stable.

AAVAD Instrument Pvt. Ltd. designs and manufactures reliable Auto Change Over Panels engineered for safe, fast, and automatic power transfer in residential, commercial, and industrial installations.

Working of ATS Panel (Auto Change Over)

The ATS Panel continuously monitors the incoming utility power supply.

Operating Sequence:

1. 1. ATS monitors the mains power supply

   2. On mains failure, the panel sends a start command to the standby generator

1. After the generator stabilizes, the load is transferred automatically

2. Emergency power is supplied to critical loads

3. Once utility power is restored, the ATS transfers the load back to mains

4. The generator runs for a cooling period and then shuts down automatically

This automatic operation eliminates manual intervention and ensures power continuity.

ATS Controller – Intelligent Power Transfer

The ATS Controller manages the automatic transfer process using relays and software-based control logic. It controls diesel generators connected to standby loads and governs smooth load transfer during power failures.

AAVAD ATS Panels are manufactured as per Indian electrical standards, using premium raw materials and advanced technology. Panels are equipped with circuit breakers or motorized changeover switches, ensuring reliable and safe operation during mains failure.
