The dual power automatic transfer switch is a device capable of switching between two power sources. It is mainly used to detect power circuits and automatically switch the load circuit from one power source to the other. The following is the working principle of the dual power automatic transfer switch:
More Details
Switching in case of main power failure: When the main power supply (such as mains power) is cut off, the voltage is abnormal (too high/too low), or the frequency is unstable, ATS automatically detects and switches to the backup power supply (such as generator, battery, etc.).
More Details
The ATS constantly monitors the voltage, frequency, and stability of the primary power source (e.g., utility grid).If the primary power fails (outage, voltage sag/surge, or phase loss), the ATS triggers the transfer process.
