SmartGen HAT780 Dual power bypass ATS controller

* All prices on this website are retail in USD on EXW incoterms


HAT780 dual power bypass ATS controller is an intelligent dual-supply module with configurable function, automatic measurement, LCD display, and digital communication. It combines digitization, intelligence and networking. Automatic measurement and control can reduce incorrect operation. It is an ideal option for dual power bypass ATS.

The powerful Microprocessor contained within the unit allows for precision voltage (2-way-3-phase) measuring and make accurate judgment; in addition, the corresponding digital output port will active when there is over/under voltage, over/under frequency, loss of phase and other abnormal condition occurs. This controller has full consideration in various application of bypass ATS (automatic transfer system) and can be directly used for single bypass ATS and dual bypass ATS as well as manual/remote control ATS. It has compact structure, advanced circuits, simple wiring and high reliability, and can be widely used in electrical devices, automatic control and testing system of electric power, telecommunications, petroleum, coal, metallurgy, railways, municipal administration, intelligent building, etc.
