Product Description
690V 60A AHF Filter Rack Module Three Phase Three Wire Harmonic Suppression Device
Product Introduction
The ND-AHF-60-690-3W is a 690V 60A modular AHF Active Harmonic Filter system designed to eliminate harmonic oscillations and reduce operating costs. Engineered for 690V industrial power grids feeding high-power equipment, mining machinery, marine and heavy-industry applications, this system can be flexibly customized to achieve power factor improvement and load balancing, significantly improving the power quality of connected power grids.
This power-electronics based Active Harmonic Filter detects harmonic components of the load in real time and injects equal and opposite compensation currents into the grid. As a result, the grid current becomes nearly sinusoidal, harmonics are suppressed at the source, and sensitive equipment operates safely and efficiently.
Product 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, responds quickly and dynamically compensates for grid fluctuations
- Multi-Mode Treatment - Achieves 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
