In industrial practice, active filters are already being used in almost any design – optimization of the overall power system, curing the most frequent power quality problems, including, but not limited to, harmonic series redundancy and reactive conversion – becoming the norm. All active filters perform the same basic function of eliminating unwelcomed harmonics produced by non-linear devices as VFD’s and rectifiers. Incorporating modern inventions, the active filters manufactured by Sinotech Group not only improve the quality of electricity supplied to your devices but also enhance energy economy, which lowers costs and protects nature. However, what really sets our products apart is our integrated approach: we study industry specifics and offer optimum solutions.
