Active power filters have today become key components of modern electrical systems, especially in environments with nonlinear loads. These filters work by actively counteracting harmonic currents and hence help to improve the power factor and the efficiency of the system. Sinotech Group’s active power filter products are low cost and also employ high technology that addresses the increasing demands of the energy market. Besides increasing the reliability of power systems, our filters advance green energy by minimizing energy loss and enhancing efficiency in multiple industries.
