Industrial Iron Pump Control Panel for Deep Well & Return Water Pumps

Anti-Corrosion Treatment for Core Circuits, Stable Weather Resistance

The control mainboard of the 3 phase steel pump starter adopts dual protection (three-proof technology + self-developed nano-coating), significantly improving adaptability to humid and corrosive environments. It is particularly suitable for underground or semi-open equipment rooms.

17 Safety Protection Mechanisms

The iron intelligent single pump control panel integrates 17 types of fault detection and protection functions, including undervoltage, overvoltage, no-load, locked rotor, frequent startup, short circuit, and phase loss protection. When an abnormality is triggered, it automatically shuts down and displays the alarm code in real time on the LCD screen, facilitating fault troubleshooting.

The 3 phase steel pump starter tested rigorously across 11 protection, environmental, EMC, and safety criteria under IEC standards

IEC 60529：

Dust and Sand Test: Ensures that dust or sand cannot enter the internal circuitry of the controller in dusty or sandy environments.

IEC 61000：

±4kV Electrostatic Discharge Test: Verifies the controller’s immunity to±4kV electrostatic discharge, ensuring it operates reliably without crashes, restarts, or damage under ESD events.

2kV Electrical Fast Transient Burst Test: Ensures the controller remains stable and reliable under transient disturbances caused by fast switching, relay operations, motor starts, or power fluctuations, without malfunctions, crashes, or damage.

4kV Lightning Surge Test: Ensures the controller operates safely and reliably under real-world lightning strikes or sudden high-voltage surges.

IEC 60068：

70°C / 95%RH Temperature and Humidity Cycling Test: Verifies the controller’s stability and long-term reliability under extreme climate conditions.

Vibration Resistance Test: Ensures the controller maintains stable performance under transportation and operating vibrations.

55°C±5°C High Temperature Burn-in Test: Each controller runs for 96 hours at high temperature to detect potential issues early and ensure long-term reliability.

IEC 60950 / 60335：

650℃Glow Wire Test: meeting electrical safety standards with excellent flame resistance.

AC Hipot Test: Ensures the controller can withstand high voltage without insulation breakdown.

Insulation Resistance Test: Confirms excellent insulation performance to prevent leakage and ensure long-term safety.

SPD Thermal Stability Test: Ensures the surge protector remains safe and stable under high temperature and abnormal voltage, preventing fire hazards and guaranteeing long-term reliability of the controller.

Remote Communication Expansion, Convenient System Linkage

The iron intelligent single pump control panel supports an optional RS485 interface (compatible with Modbus RTU protocol), which can be easily integrated into upper systems such as SCADA, PLC, and centralized control. This facilitates remote data collection and operation optimization for projects.

Installation Steps Recommendation

Ensure installation is carried out after power-off to avoid electric shock risks.

Fix the controller on a solid wall or inside the control cabinet.

Complete wiring according to the wiring diagram and check that terminal crimping is secure.

If remote function is enabled, use industrial-grade shielded wires and route them away from high-voltage power lines.

Operation and Configuration Tips

After power-on, the iron intelligent single pump control panel automatically enters the main page; press the SET key to enter parameter setting.

Set operation logic, start-stop time periods, and protection parameters.

The LCD screen displays real-time voltage, current, operation time, and fault codesfor easy maintenance.

Q1: How many wires are needed for the input power supply of the 3S three-phase iron enclosure controller?

A1: Only 3 live wires are required. The 3 phase steel pump starter is equipped with a standard grounding wire (no neutral wire needed); a neutral wire is only required for controllers without grounding design.
