AHF 690V Three Phase Active Harmonic Filter Cabinet
Product Introduction
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-500 AHF cabinet delivers accurate, efficient and safe harmonic control.
Product Features & Characteristics
Main features of the AHF Active Harmonic Filter Cabinet low voltage electrical equipment:
Covers 2nd to 51st harmonic elimination (full or directional) with a compensation rate of ≥ 95% and millisecond-level response (≤ 20 ms). No resonance risk, suitable for dynamically fluctuating loads.
Compatible with 380V-690V power distribution and three-phase three-wire/four-wire systems, with drawer, wall-mounted and vertical installation types.
Multiple AHF cabinets support parallel operation for capacity expansion, with customizable protection class for different sites.
Connected in parallel without modifying the original power distribution system, with built-in overvoltage, overcurrent and other protections and automatic cut-off in case of fault.
Equipment efficiency ≥ 97.5% and power consumption as low as ≤ 2%, effectively saving energy in long-term operation.
Visual touch screen for real-time parameter monitoring, RS485 communication for remote and networked management, and industrial-grade components requiring no frequent daily maintenance.
Ultra-compact modular design with a maximum switching frequency of 25.6 kHz and industry-leading thermal dissipation technology.
Supports continuous power factor correction with capacitive and inductive reactive power compensation, maintaining power factor within -1.0 ~ +1.0, controlling three-phase unbalance to less than 5% and reducing neutral current.
