Product Description
Product Name: 3P4W AHF 100A harmonic filter wall mounted office building using
Wall mounted SFR-AHF which intergrated with 4" HMI control system uses an efficient power electronics topology and advanced all-digital control technology to dynamically eliminate harmonic currents.
Working Principle
The AHF acquires the current signal of the load by the CT, separating the harmonic by the intelligent FFT(Fast Fourier Transform) by the DSP then send to the internal IGBT by the PWM signal. The AHF will generate the compensation current with the same value but opposite phase as the system harmonic in order to achieve the real-time dynamic filtering function.
Application
SFR-AHF can be widely used in the following industrial fields (steel industry, metallurgy industry, mining industry, new energy industry, automotive industry), municipal field (water treatment industry, telecommunications industry, research institutes), commercial field (hospital, bank, shopping mall , schools, computer rooms, computer centers), rail transportation (electrified railways, subways).
