The unit comes with built-in communication interfaces and supports remote monitoring via mobile APP paired with WIFI/4G modules. The controller integrates protection against pump overload, dry-run due to water shortage, locked rotor, undervoltage and overvoltage, with an IP65 high ingress protection rating.
• Remote Communication: Built-in network communication interface, supporting remote monitoring via mobile APP and WIFI/4G modules. Real-time voltage and current display, timing configuration and fault alert push available.
• Control & Protection: Compatible with pulse electrode probes, float switches, 3-wire pressure gauges and 2-wire pressure switches. Direct switching between liquid level and pressure control, manual / automatic dual operation modes. Protection functions include overload, dry-run, locked rotor, undervoltage and overvoltage protection.
• Display & Maintenance: High-definition Chinese LCD dynamic display, one-click quick parameter setting. Built-in spindle anti-rust jog program, cumulative running time query, cloud remote monitoring and RS485 communication supported.
• Applicable Scenarios: Suitable for deep well pumps, submersible pumps, sewage pumps, pipeline booster pumps, centrifugal pumps and sewage lift pumps. Ideal for municipal sewage treatment, metro, industrial water treatment, building drainage and secondary water supply.
