Your Leading Active harmonic Filter Cabinet Manufacturer in China
For businesses in need of high-reliability, high-adaptability harmonic suppression solutions, Shanghai Nengdu is your premier choice. Backed by a dedicated team of senior power electronics engineers and a state-of-the-art R&D and design center, we deliver customized, highperformance Active Harmonic Filter Cabinet solutions precisely engineered to match your unique grid parameters, load profiles, and harmonic mitigation requirements.
Our Active Harmonic Filter Cabinet is available in standard colors such as black and silver and supports both ODM and OEM customization. As an active harmonic filter, the AHF Cabinet operates in parallel with the power grid and continuously monitors harmonic distortion. It then generates reverse compensation current through an inverter to dynamically neutralize system harmonics in real time.
Advantages of Our Active harmonic Filter Cabinet
Covers 2nd to 51st harmonic elimination (full/ directional), with a compensation rate of ≥95% and millisecond-level response (≤20ms). No resonance risk, suitable for dynamically fluctuating loads.
Compatible with 380V-690V power distribution and 3-phase 3-wire/4-wire systems. Multiple installation types (drawer/ wall-mounted/ vertical), support parallel operation for capacity expansion, and customizable protection class.
Parallel connection without modifying the original power distribution system. Built-in multi-protection (overvoltage, overcurrent, etc.), automatic cut-off in case of fault. Equipment efficiency ≥97.5% for energy saving.
Visual touch screen for real-time parameter monitoring, RS485 communication for remote/ networked management. Industrial-grade components, no frequent daily maintenance required.
Technology of Active Harmonic Filter Cabinet
Our active harmonic filter cabinet adopts a three-level topology with an ultra-compact modular design, featuring the fastest switching frequency of 25.6kHz, power consumption of ≤2%, and industry-leading thermal dissipation technology.
Optimal Power Quality Control
It supports continuous power factor correction, capacitive and inductive reactive power compensation, and accurately maintains the power factor within the range of -1.0 ≤ CosΦ ≤ 1.0. In addition, it controls three-phase load unbalance to less than 5% and effectively reduces neutral current.
