Solving the harmonic issues for all households! Standardizing a wide range of lineups!
The "PHF Series" is a harmonic suppression filter that efficiently and cost-effectively reduces harmonics, which are a concern for users. It can easily meet the "Harmonic Suppression Measures Guidelines" required during new installations, expansions, or updates. By installing this product, the distortion of power voltage and current waveforms is significantly reduced, improving the total harmonic distortion rate to a single-digit level. 【Features】 ■ 90% reduction in harmonic current ■ Complies with harmonic suppression measures guidelines ■ Standardized wide lineup ■ Significantly reduces harmonic current distortion *For more details, please refer to the PDF materials or feel free to contact us.
