HAT820 series dual power ATS controller is an intelligent dual-power switchover module with configurable function, automatic measurement, LCD display, and digital communication. It combines digitization, intelligence and networking together. Measurement and control process can be conducted automatically, which reduces artificial operating mistakes, so that it is the ideal option for dual-power switchover products.
HAT820 series dual power ATS controller is composed by the powerful microprocessor in the core, which can precisely measure the voltages (2-way 3-phase) and make accurate decision for abnormal voltages (overvoltage, undervoltage, overfrequency, underfrequency, phase loss, reverse phase sequence), and putout power-off control digital signal. 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 and etc.
