As the name implies, an Automatic Transfer Switch (ATS) for dual power supplies automatically connects to a backup power source when the primary power supply fails, ensuring that operations continue without interruption. Simply put, the system utilizes one primary power source and one backup source; when the primary source fails or a blackout occurs, the switch automatically transfers the load to the backup source (which, for lighter loads, can be supplied by a generator), allowing equipment to continue operating normally. Common applications include elevators, fire safety systems, and surveillance systems; UPS (Uninterruptible Power Supply) systems used by banks operate on a similar principle, though their backup source consists of battery packs.
An Automatic Transfer Switch (hereinafter referred to as the "transfer switch") is a device composed of one or more switching units and other necessary electrical components. It is designed to monitor power circuits and automatically transfer one or more load circuits from one power source to another. It is a high-performance, safe, and reliable dual-power automatic transfer switch that offers a high degree of automation and a wide range of applications.
