Product Overview:
The HAT552/HAT553 Dual Power ATS Controller is a high-performance automatic transfer module that integrates configurable logic, real-time measurement, LCD display, and digital communication. It combines digital intelligence and networking to automate power switching and reduce manual errors—making it an ideal solution for dual power systems.
HAT552 is designed for non-breaking switches
HAT553 supports non-breaking, one-breaking, and two-breaking switch types
Powered by a microprocessor, the controller accurately measures dual 3-phase voltages and responds to abnormalities such as over/under voltage, phase loss, frequency deviation, and reverse phase sequence. Its compact structure, advanced circuitry, and simplified wiring make it highly reliable and suitable for applications in power systems, telecom, petroleum, coal, metallurgy, railways, municipal infrastructure, and smart buildings.
