Description
1-Phase ABS Duplex Intelligent Pump Controller
The 1-Phase ABS Duplex Intelligent Pump Controller is a high-performance dual-pump control system designed for continuous water supply and pumping applications such as sewage lift stations, irrigation systems, and reservoir management. Supporting two pumps , the controller enables automatic duty/standby switching, alternating operation, and simultaneous pump control for reliable and efficient water management.
Designed with a flame-retardant IP65 ABS enclosure, the controller provides excellent protection against dust, moisture, and harsh environmental conditions. It supports a wide voltage range of AC110–250V and both 50Hz and 60Hz frequencies, ensuring compatibility with global electrical systems.
With support for multiple sensor types and advanced pump control logic, the controller ensures stable operation and intelligent automation. The integrated 13-protection safety system protects pumps and motors from electrical faults, dry-run conditions, and abnormal operating states, while built-in redundancy ensures continuous operation in critical applications.
