The AHF Active Harmonic Filter (AHF) Cabinet is designed and manufactured by Shanghai Nengdu for high-reliability, high-adaptability harmonic suppression. As an essential low voltage electrical equipment for power quality management, it is precisely engineered to match your grid parameters, load profiles and harmonic mitigation requirements, with standard colors of black and silver and full ODM/OEM customization support.
This low voltage electrical equipment operates in parallel with the power grid and continuously monitors harmonic distortion. It generates reverse compensation current through an inverter to dynamically neutralize system harmonics in real time. With three-level topology and an ultra-compact modular design, the AHF cabinet delivers accurate, efficient and safe harmonic control.
