    Wall Mount Active Harmonic Filter ESP-34W 35A,60A,90A & 100A ...
    Rated Power Factor (RPF) Active Harmonic Filter (APF) panels are high-performance power quality solutions that simultaneously mitigate harmonic distortion and correct power factor (achieving near 1.0 or unity) in real-time. They are essential for industrial and commercial systems with high non-linear loads like VFDs, ensuring compliant, energy-efficient operations.

    Key Features and Specifications: 
    • Capacity & Voltage: Common ratings range from 50A to over 2500A (modular) for low-voltage systems (400V, 415V, 480V).
    • Harmonic Mitigation: Filters up to 98% of harmonics, reducing THDi to less than 5%.
    • Power Factor Correction: Provides both inductive and capacitive reactive power compensation (0.99 to unity).
    • Response Time: Fast, dynamic response (typically
      <5is less than 5
      <5
       ms).
    • Design: Available in wall-mounted modules (e.g., Schneider EasyLogic) or floor-standing cabinet panels.
    • Protection: Includes overload, over-voltage, under-voltage, and over-temperature protection.

    Do harmonic filters improve power factor?
    Harmonics will always lower the PF, but can be leading or lagging or in phase. See the non-linear loads paragraph in the Wikipedia article on PF.Oct 15, 2019

    How to calculate active harmonic filter rating?
    THID/THD represents the percentage of harmonic currents relative to the fundamental current and helps in estimating the size of the AHF required to mitigate harmonics. Harmonic Current Compensation: Calculate the required harmonic current compensation by multiplying the THID/THD by the rated load current.
