Product Overview:
HAT833 Three Power ATS controller is intelligent tri-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, which is an ideal option for ATS.

The powerful Microprocessor contained within the unit allows for precision voltage (3-way 3-phase) measuring and make accurate judgment and the corresponding volt free digital output port will active when there is over/under voltage, over/under frequency, loss of phase, phase sequence wrong and other abnormal condition occurs. It has compact structure, advanced circuits, simple wiring and high reliability, and can be widely used in electrical automatic control system of electric power, telecommunications, petroleum, coal, metallurgy, railways, municipal administration, intelligent building, etc.
