The automatic transfer switch can quickly switch to a backup power source in the event of a power failure, ensuring continuous power supply to the load circuit. Through the built-in controller and sensors, the automatic switching switch can monitor the status of the power circuit in real time and automatically perform switching operations according to preset logic. The automatic transfer switch has multiple models and specifications to choose from, to meet the needs of different places and loads. The automatic transfer switch emphasizes safety in the design and manufacturing process, which can ensure the safety of operators and the stable operation of equipment.

When the commonly used power supply is detected to have deviations (such as voltage loss, overvoltage, undervoltage, phase loss, frequency deviation, etc.), the automatic transfer switch will automatically transfer the load from the commonly used power supply to the backup (or emergency) power supply. If the commonly used power supply returns to normal, the automatic transfer switch will automatically return the load to the commonly used power supply. When there is a deviation in the commonly used power supply, the automatic transfer switch will also transfer the load to the backup power supply. However, when the commonly used power supply returns to normal, the automatic transfer switch will not automatically return to the commonly used power supply, and manual intervention or backup power supply failure is required before returning.
