    AI Overview
    Parallel Rack-Mounted AHF Module 30A–150A — Compact Power ...
    The 75A Active Harmonic Filter (AHF) is a high-performance power quality device designed to mitigate electrical harmonics, correct power factors, and balance loads in real-time. It continuously monitors load current, injecting counter-currents to cancel 2nd to 50th order harmonics, crucial for protecting sensitive equipment from distortions. 
    Key Features and Benefits 
    • Harmonic Mitigation: Effectively cancels harmonics up to the 50th order (THDi < 5%).
    • Power Factor Correction: Improves power factor, reducing utility penalties and energy costs.
    • System Protection: Prevents equipment overheating, nuisance tripping, and voltage distortion.
    • High Efficiency: Operates with high efficiency, often featuring interactive touchscreens for monitoring.
    • Versatile Application: Suitable for industrial/commercial sites with high non-linear loads (VFDs, rectifiers, UPS).
    • Design Options: Available in wall-mounted or rack-mounted configurations, often with a 75A capacity. 
    Technical Specifications 
    • Capacity: 75 Amperes (75A).
    • Harmonic Compensation: 2nd to 50th Order.
    • Operating Voltage: Typically 3-phase, 4-wire, or 3-wire systems, ranging from 200V to 690V.
    • Response Time: Near-instantaneous, typically < 1 ms. 
    This device is essential for maintaining a stable, efficient, and reliable power supply, significantly extending the life of industrial electrical equipment.
