Automatic Transfer Switch (ATS) — Intelligent Switching, Continuous Power Supply
In modern power systems, stable and uninterrupted electricity supply is crucial.
When the main power source fails or goes out, the Automatic Transfer Switch (ATS) quickly transfers the load to the backup power source, ensuring that critical equipment continues running without interruption.
Whether in industrial production, data centers, or hospital facilities, the ATS is the key component that guarantees safe and reliable power delivery.
Product Overview
The Automatic Transfer Switch (ATS) is an intelligent device designed to automatically switch between two power sources.
It continuously monitors the status of both the main and backup power supplies. When it detects an abnormality in the main source (such as power loss, under-voltage, or over-voltage), it automatically switches to the backup source.
Once the main power returns to normal, it safely switches back.
The entire process is safe, stable, and fully automatic.
This product supports both manual and automatic operation modes:
In automatic mode, the switch can perform unattended power transfers.
In manual mode, users can control the switching process themselves — providing flexibility for different operating environments and needs.
