Product Introduction
Our company specializes in manufacturing submersible three phase pump control box, and we have independently developed a control panel called PLC-1, which is specifically designed for high-power cabinets. It has a small size, compact design, and wide range of applications, with the ability to control multiple pumps at once.
PLC-1 has comprehensive protection features, which allow it to automatically adjust the pump's normal working status based on the input current, providing protection against dry running and overload current. It can receive signals from both digital and analog probes, enabling automatic start-stop control of the pump.

The built-in passive dry contact can output fault signals and start-stop signals for the pump.
Furthermore, PLC-1 is equipped with a 485 interface, which enables remote control. The panel's advanced technology and reliable performance make it an ideal choice for various water pump control applications. At our company, we are committed to providing our customers with high-quality products and the best possible service.
