Waterproof Frequency Inverter | IP54 Rated For Industrial/Pump Use | 220V-440V VFD Drive

I. Key Features (Compared to 110V-480V Model)

1. Voltage Range Adjustment
   • Coverage: 220V-440V AC (three-phase), focusing on medium and high-voltage industrial applications, compatible with mainstream three-phase voltage standards in Europe (400V) and North America (440V).
   • Compatibility Optimization: Designed for three-phase motors, reducing the need for single-phase power adaptation and enhancing stability in industrial environments.
2. IP54 Protection Rating
   • out V900 Series frequency inverter , it offers dust and water splash resistance, suitable for humid and dusty environments such as pump rooms and outdoor installations.
3. Power and Performance
   • Power Range: Typically covers 1.5kW to 315kW (some industrial models support higher power), meeting the needs of medium to large industrial pumps.
   • Control Precision: Supports vector control (closed-loop/open-loop) with faster dynamic response and higher speed regulation accuracy (±0.1%), suitable for high-precision industrial processes.

II. Typical Applications

1. Industrial Pumps
   • Multistage Centrifugal Pumps: Supports high-pressure and large-flow water supply (head ≥200m, flow ≥500m³/h), suitable for municipal water supply and agricultural irrigation.
   • Chemical Pumps: Corrosion-resistant design, compatible with acid/alkali media, and supports explosion-proof certifications (ATEX/IECEx).
2. Circulating Water Systems
   • In industries like steel and power, it optimizes cooling water flow through variable frequency speed regulation, reducing energy consumption by over 35% and minimizing water hammer effects in pipelines.
3. HVAC Systems
   • Integrated into central air conditioning chilled water pumps, it automatically adjusts speed based on load, achieving energy savings of 30%-50%.
4. Other Industrial Equipment
   • Suitable for rotating equipment requiring wide voltage range and high protection ratings, such as extruders and compressors.
