Shanghai 3S Global Company Limited
The 3S dedicated smart control box series is engineered for specialized applications such as sewage lifting, municipal drainage,HVAC, pressure boosting, and emergency firefighting. Each model includes scene-specific logic, protection functions, and optimized control algorithms to ensure reliable operation in harsh or demanding environments such as high corrosion, high humidity, deep heads, and frequent start-stop cycles.
By monitoring current waveforms, the controller detects impeller jams or blockages, warns early, and cuts power to prevent motor damage.
Supports DOL, star-delta, and soft start—smooth ramping and delayed signals prevent pressure surges and water hammer, protecting pipelines.
Supports RS485, Wi-Fi, and IoT—enabling real-time monitoring of operations, alarms, and historical data, plus interactive communication with the control center.
