Product Name
Product Introduction
The ND-AHF-300-400-4W is a 300A 400V cabinet AHF Active Harmonic Filter AHF system designed to eliminate harmonic oscillations and reduce operating costs. It is engineered for large industrial facilities, commercial complexes and data centers requiring high-capacity harmonic mitigation with room for future expansion, and can be flexibly customized to achieve power factor improvement and load balancing, significantly improving the power quality of the connected power grid.
The ND-AHF-300-400-4W is a power-electronics based Active Harmonic Filter AHF which 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.
