1 OVERVIEW
HAT552/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.
HAT552/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.
