Product Name

60A 480V Wall Mounted Active Harmonic Filter AHF Low Voltage Three Phase Four Wire Compact Harmonic Suppression Unit

Product Introduction

The ND-AHF-60-480-4W is a 60A 480V wall-mount AHF Active Harmonic Filter AHF system designed to eliminate harmonic oscillations and reduce operating costs. It is engineered for low voltage distribution systems below 1 kV, including 400V and 480V grids in commercial, civil and general industrial applications, 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-60-480-4W 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.
