Industrial Pump PCBA – Heavy‑Duty Controller with Dry‑Run Protection, Overload Cutoff, Pressure/Flow Regulation & Remote Monitoring for Commercial/Agricultural Pumps
No.YQQX042
- Robust Motor Control – Drives 3‑phase induction motors (up to 5HP / 3.7kW) via contactor or soft‑starter interface. Supports single‑phase 110‑240V AC or 3‑phase 380‑480V AC input. Built‑in phase loss and phase imbalance detection.
- Dry‑Run Protection – Low‑water sensor input (float switch, conductivity probe, pressure switch, or electrode) – shuts down pump when water level below minimum. Auto‑restart delay (adjustable 1‑60 minutes) after water refill.
- Overload & Overcurrent Protection – Current transformer (CT) or shunt‑based sensing. Programmable overload threshold (100‑120% of rated current). Trip delay: inverse time curve (IEC 60947‑2 compliant). Manual or auto‑reset after fault.
- Pressure & Flow Regulation – PID control loop using pressure transducer (4‑20mA / 0‑10V) or flow sensor. Maintains constant pressure or constant flow for variable demand systems – reduces energy consumption by 20‑40% vs. fixed‑speed pumps.
- Remote Monitoring & Alerts – Optional 4G/Wi‑Fi/RS485 (Modbus RTU) module for connectivity. Real‑time data: pump status (on/off), current, pressure, flow, runtime hours. Push notifications for faults (dry‑run, overload, phase loss). Compatible with SCADA and building management systems.
- Applications – Suitable for: industrial water supply, irrigation pivots, booster pump stations, wastewater treatment, mining dewatering, HVAC chilled/hot water circulation, and agricultural spraying systems. IP54 / NEMA 3R enclosure option for outdoor or dusty environments.

Product Overview
The Industrial Pump PCBA is a heavy‑duty electronic controller designed for commercial, agricultural, and light industrial pumps (centrifugal, submersible, deep well, booster). It replaces traditional electromechanical relays and pressure switches with microcontroller‑based intelligence, offering dry‑run protection, overload protection, PID regulation (constant pressure/flow), remote monitoring, and fault diagnostics.
This PCBA accepts direct 110‑480V AC input and controls pumps up to 5HP via external contactor. It protects pumps against dry running (burnout), overload, phase loss, and voltage imbalance – reducing downtime and maintenance costs. With optional communication modules (RS485, 4G, Wi‑Fi), it enables remote operation and integration into automation systems, making it ideal for applications where pumps run unattended for long periods.
