3S-31-PA simplex pump intelligent control panel-The Ideal Choice to Reduce After-Sales Pressure for Assemblers

The 3S-31-PA Panelis tailored for controller assemblers to minimize after-sales risks from the source. This digital smart pump controller integrates intelligent protection and fault diagnosis functions, while high-quality components ensure stable pump unit operation. It significantly reduces pump failure rates and after-sales service demands, boosting delivery efficiency and customer satisfaction.

1. 17 Intelligent Protection Features to Reduce Fault Risks

Comprehensive motor protection: Covers overload, underload, locked rotor, dry running, overvoltage/undervoltage, phase loss, and three-phase imbalance, ensuring safe pump operation under all working conditions.

Electrical protection design: Includes surge protection (MOV, TVS), lightning protection, anti-static measures, and anti-electromagnetic interference, directly reducing after-sales disputes related to the simplex pump intelligent control panel caused by electrical faults.

Environmental protection: Equipped with the company’s independently developed, China-first waterproof PCB, which also provides dust and corrosion resistance. This digital smart pump controller adapts to high-humidity and high-temperature environments, significantly lowering maintenance needs.

2. Fault Visualization and Alarm

The LCD screen of the simplex pump intelligent control panel displays real-time operating status and fault codes, allowing assemblers and end-users to quickly identify the source of problems.

System self-inspection and sensor fault prompts improve fault detection efficiency and reduce on-site troubleshooting time.

Automatic parameter calibration: When uncalibrated, it issues an audible and visual alarm and displays "Not Set Current" on the LCD to prevent pump damage caused by uncalibrated startup.

Automatically saves and retrieves the last 10 fault records, facilitating tracking and predictive maintenance.

3. Self-Learning and Easy Debugging

The digital smart pump controller can automatically record the pump’s rated current and save it to parameters, greatly reducing manual debugging errors.

A lock screen password prevents unauthorized operations, ensuring the operational security of the system.

Power-off memory and automatic recovery: Ensures continuous system operation by automatically restoring to the pre-power-off state after a power outage.

4. Standardized and Expandable Design

Modular structure enables quick replacement or function addition, lowering the complexity of after-sales maintenance.

Standardized terminals and interfaces allow assemblers to install quickly and adapt to various pump types.

Expandable functions: Remote control (RS485/IoT/WiFi), timing control (cycle/24-hour timer), and multi-group signal terminal expansion, flexibly meeting different project requirements.

Flexible assembly of multiple startup methods: The simplex pump intelligent control panel can be configured with DOL (0.37–7.5 kW), star-delta (7.5–30 kW), auto-transformer reduced voltage starting (30–300 kW), and soft start (30–500 kW) modes. It can be assembled flexibly according to project needs, minimizing after-sales troubles caused by incompatibility.

5. High-Quality Components to Ensure Overall Reliability

Industrial-grade MCU (ST industrial chip) and HONGFA relays ensure stable performance and long service life of the digital smart pump controller.

High-precision current transformers (current calibration accuracy: 0.01A): Ensure accurate current collection, improve the reliability of protection logic, and reduce false or missed triggers.

Switching power supply transformer: Compatible with rated voltages of 110–415V, effectively preventing controller damage caused by voltage fluctuations.

Optimized PCB design: Integrates surge protection, lightning protection, anti-static measures, and signal isolation, reducing faults caused by component differences or external environments.

Wide-pitch FPC connectors: Increase creepage distance, effectively preventing leakage and arcing risks (compliant with IEC 60664 standard).

Strict manufacturing processes and 14 traceable quality inspections ensure consistency and reliability of each simplex pump intelligent control panel.

Centered on high reliability, intelligent protection, fault visualization, and modular design, the 3S-31-PA digital smart pump controllerhelps controller assemblers significantly reduce after-sales service needs, lower on-site maintenance difficulty, and improve overall machine delivery efficiency and customer satisfaction. Whether for diverse project types or pump models, it provides a stable and reliable control solution, making every delivery safer and more efficient.
