HMAT821 Series Medium Voltage Bus Tie ATS Controller is a module that integrates configurable function, automatic measurement, PT break detection, LCD display and digital communication. It combines digitization, intelligence and networking, the automatic measurement and control process can reduce incorrect operation, which is an ideal option for medium voltage bus-tie transfer.
HMAT821 Series Medium Voltage Bus Tie ATS Controller is composed of microprocessor as the core, which can precisely detect 2-way 3-phase incoming voltage, make accurate judgment for voltage abnormal situations (over/under voltage, over/under frequency, loss of phase, reverse phase sequence) and output passive control coil. With compact structure, advanced circuits, simple wiring and high reliability, it can be widely used in electrical automatic control system of electric power, telecom, petrochemical industry, mining, railways, municipal administration, data center, intelligent building and other industries.
