UPS Input to ATS Distribution Panel | Dual Power Supply Automatic Transfer Switch is a general-purpose dual power supply automatic switch-over device. This product can simultaneously input two independent AC380V, 500KW power supply branches, i.e., main power and backup power. When the main power circuit stops, the backup power branch automatically switches on within 20 seconds to supply power to the load. Upon the restoration of the main power supply, the dual power supply controller automatically switches back to the main power supply, and the backup power supply stops. The dual power supply controller is equipped with a CPU and HMI operation interface, featuring circuit scheme flowcharts, status indicators, fault indicators, and forced switch buttons. The product employs a safe circuit design, ensuring reliable and safe operation. The dual power switch uses advanced control modules with comprehensive logic as the foundation for the transfer cabinet design. It can work with various automatic function generators of different brands and models, initiating and stopping the generators through a single-card module to complete a complete city power and generator automatic conversion system. It is also suitable for other scenarios where no power switching between two power sources is required and is widely used in industrial and mining, enterprises, post and telecommunications, and other important power-consuming departments. The entire cabinet is designed to meet customer requirements, making installation, adjustment, and maintenance very convenient for users when necessary.
