HAT553 dual power ATS controller is a dual power transfer module integrated with configurable function, automatic measurement, LCD display, and digital communication. It combines digitalization, intelligence and networking together, which realizes automation for measuring and control process, reducing artificial operation mistakes. It is the ideal product for dual power transfer. HAT552 is applicable for non-breaking switches, while HAT553 is applicable for non-breaking, one-breaking, and two-breaking switches.
HAT553 dual power ATS controller is made with the microprocessor in the core, which can precisely measure 2-channel 3-phase voltages, make correct judgment and control outputs for occurred voltage abnormal (over voltage, under voltage, loss of phase, over frequency, under frequency, reverse phase sequence). 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.
