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.

An automatic transfer switch is an electrical device composed of one or more transfer switch devices and other necessary devices, used to monitor power circuits (such as voltage loss, overvoltage, undervoltage, phase loss, frequency deviation, etc.), and automatically convert one or more load circuits from one power source to another. In the electrical industry, it is also known as a "dual power automatic transfer switch" or "dual power switch.".
