APFC or Automatic Power Factor Control Panels are mainly used for the improvement of Power Factor. It has a microcontroller based programmable controller which switches the capacitor banks of suitable capacity automatically in multiple stages by directly reading the reactive load (RKVA) which works in the principle of VAR sensing tends to maintain the PF to 0.99 Lag. The capacitor banks may be selected in number of stages according to the load pattern. The power factor can be maintained by installing Automatic Power Factor Control Panel (APFC Panel)
