PFCS Datasheet, PDF (1/4 Pages) Cornell Dubilier Electronics – 3-Phase AC Power Factor Correction Capacitors

Type PFCS, 3-Phase AC Power Factor Correction Capacitors
Type PFCS 3-phase series capacitors are designed for power factor
correction in automatic PFC controllers. Each PFCS capacitor is
made with three self-healing metallized polypropylene windings,
connected in delta, enclosed in a cylindrical aluminum case and
filled with an environmentally friendly fluid.
