HAT880 Series Dual Power Bypass ATS Controller is an intelligent dual power bypass switch module which integrates programmable function with automatic measurement, LCD display and digital communication. It is with qualities of digitalization, intelligence, and network. Meansurement and control automation is realized for reducing human operation mistakes, so it is the ideal device for dual power bypass switch. 
HAT880 Series Dual Power Bypass ATS Controller is composed of micro-processor, which is the core in the controller, and can precisely detect 2-way 3-phase power, making correct judgment for abnormal power statuses (over voltage, under voltage, loss of phase, over frequency, under frequency) and outputting free voltage control signals. After overall consideration about its bypass switch application, it can be used directly on single and dual bypass switches, and manual or remote control switches. It is with compact structure, advanced circuit, simple wiring, and high reliability, and can be widely used in electrics, telecommunications, petroleum, coal, metallurgy, railway, municipal administration, intelligent building fields, electric installations, servicer power supply and debug system.
