Product Description

The IP65 booster pump controller is specifically designed for large-scale industrial booster pump stations and main pump control in regional water plants. It needs to be integrated into systems via the RS485 protocol to achieve precise control of high-power pump sets.

 

Full Power Range & Voltage Compatibility

Power Range: 4.0 kW to 30 kW coverage for various applications

Voltage Support: Three-phase AC input from 220V to 415V (±10%), compatible with multi-country industrial grid standards

Simplified Selection: Eliminates custom procurement costs and delays

 

Robust Enclosure & Protection

ABS Enclosure: High-strength engineering plastic with IP65 rating, excellent impact and UV resistance

PCB Protection: Coated with three-proof paint and self-developed protective layer for moisture and salt spray resistance

Operating Range: -20°C to +55°C for harsh environments

This makes the IP65 booster pump controller suitable for various high-humidity, high-dust, or coastal project environments.

Typical Applications

Application Scenario

On-Site Challenges

3S Controller Solution

Industrial Cooling System

Intensive power consumption inside the factory causes local voltage instability.

Insufficient water source or pipeline blockage leads to pump idling or locked rotor, damaging the motor and impeller.

The IP65 booster pump controller supports wide voltage input of 220–415V, unaffected by voltage fluctuations.

Combined with dry run and locked rotor protection, as well as automatic shutdown and restart logic, it extends equipment life and reduces maintenance costs.

Commercial Building Water Supply System

Frequent pump start-stop cycles during peak demand accelerate equipment wear and increase failure risk.

The pump control panel features built-in signal-based start-stop delay to minimize frequent cycling.

Coupled with anti-cycling protection, it reduces mechanical stress and extends the service life of pumps and the overall water supply system.

Frequently Asked Questions (FAQ)

Q1: Does it support the commonly used 380V three-phase industrial power grid?

A1: Yes, the IP65 booster pump controller supports three-phase input of 220–415V, which is suitable for common industrial power grids. Please confirm the voltage match during installation to ensure the normal operation of the equipment.

 

Q2: Does the equipment record historical fault information?

A2: Yes, the three pump intelligent pump control starter device can store the latest 10 fault records. Press the【Fault Record】key to enter the fault record page, and press the "▲,▼" keys to query the latest 10 fault records.
