FRANKE – GMKPc800II POWER FACTOR CONTROLLER (PFC)
GMKPc800II PFC 14 STEPS ( CAN MEASURE INDIVIDUAL HARMONIC ) SIZE 144×144 mm. ( CUT 138×138 mm. )
Reactive power compensation plants are used to decrease the load of cables and power distributions caused by inductive currents and to save reactive power costs. The power factor controller is a main part of such a plant and connects or disconnects capacitor stages automatically. The series GMKPc power factor controllers are suitable for the use in conventional or special dynamic reactive power compensation systems and a mixed operation is possible as well.
