KTY3S
Multi-function Three-phase Power Controller

The KTY series three-phase power controller is a powerful product that integrates various control modes including open-loop, constant voltage, constant current, and real RMS voltage and current measurement for accurate active power control. It offers a rich set of interfaces supporting multiple switch and analog programming inputs, enhanced by isolation technology to improve noise immunity. The standard RS485 communication interface and expandable options like PROFIBUS ensure seamless integration into diverse systems. Its heavy-duty design and robust overload capability guarantee long-term stability. Widely used in industrial furnaces, machinery, glass manufacturing, and other sectors, this controller delivers efficient and reliable power control solutions.
