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- 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.
- 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.
- 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.
- 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.
- 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.
