ATS controller HAT833

Three Power ATS Controller is intelligent tri-supply module with configurable function, automatic measurement, LCD display, and digital communication. It combines digitization, intelligence and networking. Automatic measurement and control can reduce incorrect operation, which is an ideal option for ATS. The powerful Microprocessor contained within the unit allows for precision voltage (3-way 3-phase) measuring and make accurate judgment and the corresponding volt free digital output port will active when there is over/under voltage, over/under frequency, loss of phase, phase sequence wrong and other abnormal condition occurs. 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. System type can set as: Mains-Mains-Gen, Mains-Mains-Mains, Mains-Gen-Gen, etc; 4.3 inchs solid color 240x128 LCD display with white backlight, multilingual interface (including English, Simplified Chinese or other languages), push-button operation; Collect and display 3-way 3-phase voltage, frequency and phase sequence; Collect and display load active power, reactive power, apparent power, power factor and current; S1/S2/S3 separated over current warning/ trip alarm; NEL (Non-essential Load) trip function; Display S1/S2/S3 total kW energy, total kvar energy, total close times; Display continuous power supply time and S1/S2/S3 total power supply time; For Stored-Energy type ATS, its close relay will active after the PF Input is active;
