What is Automatic Transfer Switch
An Automatic Transfer Switch (ATS) is a specialized electrical device for dual‑power distribution systems. It monitors the power status of the main and standby power sources in real time. When the main power encounters failures such as power outage, undervoltage or phase loss, it automatically switches quickly to the standby power supply to ensure uninterrupted power for critical equipment. Featuring mechanical and electrical double interlocks, it prevents short‑circuit caused by parallel connection of two power sources and supports automatic and manual control modes.

Frequently Asked Questions
How does ATS work in electrical?
The core function of an Automatic Transfer Switch (ATS) is to monitor parameters such as voltage, frequency and phase of two power sources in real‑time. Under normal conditions, the main power supply feeds the loads. When the main power fails due to power outage, undervoltage, phase loss or overload, the internal controller of the ATS rapidly triggers the mechanism to switch automatically to the standby power supply.
Equipped with mechanical and electrical double interlocks, it prevents short‑circuit caused by parallel connection of two power sources. Continuous monitoring is maintained after switching, and it can switch back automatically once the main power is restored to ensure uninterrupted power supply.
Is an ATS an UPS?
An Automatic Transfer Switch (ATS) is not the same as an Uninterruptible Power Supply (UPS). The ATS is a power‑switching device that only switches to the standby power supply when the main power fails, with a brief power interruption during switching. In contrast, a UPS has built‑in energy‑storage batteries and supplies power instantly after an outage to achieve zero‑interruption power supply. They are often used together: the UPS ensures instantaneous power supply, while the ATS handles long‑term switching between main and standby power sources, jointly guaranteeing stable operation of critical equipment.
How to install and maintain ATS equipment?
ATS installation requires standard cabinet mounting and reliable earthing. Separate the main power, standby power and load circuits, fasten wiring after phase‑sequence verification, adjust parameters such as switching delay, and test double interlocks and switching functions.
For routine maintenance, regularly remove dust, inspect terminals, contacts and indicators, and check for overheating or loose connections. Simulate power outages periodically to test switching performance and replace aging components promptly to ensure reliable operation during faults.
