This 220V Low Voltage Inverter integrates vector control technology to deliver precise motor speed regulation for industrial and commercial applications. Designed for compatibility with single/three-phase 220V power grids, it optimizes energy efficiency while ensuring stable operation of pumps, fans, conveyors, and HVAC systems. Its advanced control algorithms and robust protection features make it ideal for demand-responsive environments.

• Field-Oriented Control (FOC):
  Decomposes stator current into flux (d-axis) and torque (q-axis) components for independent control, achieving ± 5% speed accuracy and 150% torque at 0.5Hz.
• Dynamic Response:
  Rapid torque adjustment (e.g., 200% torque at zero speed) for elevator/hoist applications.

• IE4 Compliance:
  Reduces energy consumption by 30-50% compared to fixed-speed systems. A 75kW chiller pump saved $12,500/year in energy costs.
• SVPWM Technology:
  Minimizes harmonic distortion, improving efficiency by 2-5% over standard V/F control.

• Overload Handling:
  150% overload capacity for 1 minute, protecting motors from transient overloads.
• Fault Resilience:
  Auto-restart after voltage recovery and bypass to mains power during severe faults.
• Environmental Adaptability:
  Operates at -10 °C to 50°C, with IP20 options for dusty/wet environments.

• Industry 4.0 Integration:
  Supports BACnet for HVAC systems and Profinet for industrial automation.
• Remote Monitoring:
  Cloud-based platforms enable real-time performance tracking and predictive maintenance.

• Mounting: Wall-mounted or DIN-rail, with ≥15cm clearance for ventilation.
• Wiring:
  • Use shielded cables for control signals to reduce interference.
  • Separate power and control circuits.
• Commissioning:
  Auto-tuning for motor parameters (resistance, inductance) ensures optimal control.

• Routine Checks:
  Clean cooling fans quarterly, inspect terminals for corrosion.
• Firmware Updates:
  USB/Ethernet interface allows parameter backup and firmware upgrades.
• Diagnostics:
  Real-time fault codes and historical data via HMI or SCADA integration.
