ATS controller HAT820

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. System type can be set as Mains-Power Generation, Power Generation-Mains, Mains-Mains, Power Generation-Power Generation; 4.3-inch large LCD Display of single color, 240x128 pixel with white backlight, multiple language display (Simplified Chinese, Engligh, and Other), default language for Other is Traditional Chinese, and tuch-button operation; Collect and display 2-way 3-phase voltages, frequency and phase sequence; Collect and display loading active power, reactive power, apparent power, power factor and current; Independent over current warning and trip alarm functions for S1 and S2; NEL trip function;
