Elecnova SFR-L series power factor correction intelligent low voltge capacitor are mainly used for reactive power compensation in the fields where harmonics are not very serious. They are suitable for local compensation, dispersion compensation and centralized compensation. This series of products adopt double zero-crossing switch technology to make sure there is no over voltage or high inrush current during capacitor switching so as to prolong capacitor life and switch life. SFR-L series capacitor modules have many protection functions such as capacitor internal temperature protection, grid harmonic content protection, over current protection, over voltage protection and three phase unbalance protection which make them more reliable.
