ACI Low Power Water Pump Dedicated Frequency Converter

Low-Power Water Pump Dedicated Frequency Converter is a specialized device designed to control the speed of small-capacity water pump motors by adjusting the frequency of the power supply. This allows for precise regulation of water flow and pressure while achieving significant energy savings.

Key Features

1. High Energy Efficiency:
   • Typically achieves energy savings of 20%–60% compared to traditional water supply methods, depending on actual operating conditions.
   • Reduces energy consumption by matching the pump's speed to the actual demand, avoiding unnecessary high-speed operation.
2. Constant Pressure Control:
   • Utilizes advanced pressure-sensing technology to maintain stable water pressure, ensuring consistent supply even under varying demand.
   • Supports multi-pump systems with automatic switching and soft start/stop functions, balancing the load and extending equipment lifespan.
3. Intelligent Control:
   • Equipped with PID (Proportional-Integral-Derivative) control algorithms for precise pressure regulation.
   • Features like sleep mode, dry run detection, and automatic energy optimization further enhance efficiency and reliability.
4. Compact Design:
   • Small footprint and lightweight, making it suitable for space-constrained environments such as residential buildings, small-scale irrigation systems, and compact industrial applications.
5. Advanced Protection Functions:
   • Includes overcurrent, overvoltage, undervoltage, overload, short circuit, phase loss, and overheat protection.
   • Self-diagnostic capabilities simplify maintenance and reduce downtime.

Technical Specifications

• Power Range: Typically available from 0.75kW to 7.5kW, accommodating various small pump sizes.
• Frequency Range: 0–50Hz or higher, depending on the model, allowing for wide-range speed adjustment.
• Control Interface: Supports RS485, Modbus, and other communication protocols for remote monitoring and centralized management.
• Protection Level: Often rated IP55 or higher, suitable for harsh environments.

Advantages

• Soft Start/Stop: Eliminates water hammer effects, reducing wear and tear on the pump and extending its service life.
• Reduced Maintenance: By operating at optimal speeds, the pump experiences less stress, leading to lower maintenance costs.
• Environmental Benefits: Reduces energy consumption and carbon footprint, contributing to sustainable water supply solutions.

Application Examples

• Residential Water Supply: Ensures stable water pressure in small buildings or apartments, preventing issues like low pressure on upper floors.
• Small-Scale Irrigation: Optimizes water usage in gardens, greenhouses, or small farms by adjusting pump speed according to soil moisture and crop needs.
• Aquarium and Fountain Systems: Maintains precise water flow and pressure for aquatic life and aesthetic displays.
• Lab and Industrial Cooling: Provides controlled water circulation for small-scale equipment cooling in laboratories or light industrial settings.
