OVERVIEW
HAT553V
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. HAT553V is
applicable for non-breaking, one-breaking, and two-breaking switches.
HAT553V
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, over frequency, under frequency, loss of phase, 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.
