Active Harmonic Filter Panel 400V 50/75/100/150 APF for Industrial Power Quality Improvement

Product Description

Product Highlights
  • The GY-APF Series Active Power Filters (APF) are connected in parallel with the power grid to continuously detect harmonic currents and reactive power components generated by non-linear loads, including VFDs, rectifiers, and switching power supplies. By leveraging advanced PWM (Pulse Width Modulation) technology, the APF injects equal-but-opposite compensation currents into the distribution system, achieving three core objectives:
    • Suppression of Harmonics (up to the 50th order)
    • Dynamic Reactive Power Compensation
    • Three-Phase Load Balancing
  • APF Active Power Filters: A rugged, high-performance variant engineered for demanding environments. Capacity Range: 50–150 A. Applications: Heavy industry, commercial buildings, sites with high single-phase loads, and harsh operating conditions. Advanced Features: Dual DSP controller architecture for ultra-fast, stable response. Real-time temperature monitoring and fan alarm functions. Precise fault feedback for simplified maintenance.
  • Improved Power Quality: Reduces harmonic distortion and corrects power factor.
  • Enhanced Equipment Reliability: Protects motors, transformers, and sensitive electronics from harmonic damage.
  • Energy Savings: Lowers energy consumption and reduces utility penalties for poor power factor.
  • Easy Integration: Rack-mount design for simple installation in standard cabinets.
  • Proactive Monitoring: Industrial models offer comprehensive diagnostics and protection features.
