Description
1-Phase Stainless Steel Simplex Intelligent Pump Controller
The 1-Phase Stainless Steel Simplex Intelligent Pump Controller is designed for reliable pump control in high-humidity and corrosive environments. With a corrosion-resistant stainless steel enclosure and IP55 protection, this controller is ideal for coastal water supply systems, underground wells, agricultural irrigation, and other demanding applications.
The controller supports a wide input voltage range of AC110–250V, making it compatible with global power grids without the need for additional transformers. Its advanced monitoring system and 13 integrated protection functions ensure safe and efficient pump operation while minimizing maintenance costs and downtime.
With support for multiple sensor inputs and optional remote communication via RS485, IoT, and Wi-Fi, the controller can easily integrate with modern automation systems for centralized monitoring and control.
