Wall Mounted Active Harmonic Filter

1. Product Overview

CoEpower wall-mounted series Active harmonic filters（AHF for short ) is a more flexible installation with excellent compact modular design, The Maximum size for the single module is 150A, and it also can be connected in parallel as a floor stand cabinet solution. Hanging on the wall saves much space and also offers good convenience to space-limited installation sites.

CoEpower Active harmonic filter is based on IGBT-based inverter functions of dynamic harmonic compensation (varying amplitude and frequency) and reactive power compensation (leading or lagging). This AHF works by injecting in a current of the same magnitude but opposite in phase in the distorted electric power system to offset the harmonic, thus reaching a THDI of less than 5%, The advanced NPC 3-level topology design, and DSP+FFT high-speed operational capability supports a stable ultrafast working performance without overload.
