PTS-WST-9 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, over frequency, 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.
