Product Description

600A 400V Active Harmonic Filter AHF Floor Standing Cabinet

Product Overview

The ND-AHF-600-400-4W is a 600A 400V high-capacity Active Harmonic Filter system designed to eliminate harmonic oscillations and reduce operating costs. Engineered for heavy industry plants, steel and metal processing, automotive production lines, and large commercial loads with severe harmonic pollution.

This power-electronics based AHF detects harmonic components of the load in real time and injects equal and opposite compensation currents into the grid, resulting in nearly sinusoidal grid current and suppressed harmonics at the source.

Key Features

Highly Efficient & Precise Harmonic Filtering Eliminates 2nd to 50th harmonic disturbances with high precision for comprehensive harmonic treatment.
Fast Response & Dynamic Compensation Monitors load changes in real time with quick response to dynamically compensate for grid fluctuations.
Multi-Mode Treatment Comprehensive management of harmonics, reactive power and three-phase imbalance in one unit.
Efficient, Safe & Stable Operation Operates in coordination with the power grid without resonance risk, ensuring long-term stable performance.
Modular Design for Easy Installation Compact size with small footprint, suitable for space-constrained installation scenarios.
Strong Load Adaptability Automatically adjusts parameters under frequently changing load conditions to maintain stable operation.
Energy Saving & Equipment Protection Effectively reduces line losses and equipment heating, extending the service life of electrical equipment.
Flexible Capacity Expansion & Excellent Scalability Supports modular parallel expansion for easy capacity upgrading without system reconstruction.
