Metalized polypropylene film capacitor PhiCap

cylindricalPFCpower-factor correction

Overview
PhiCap MKP capacitors are metalized polypropylene (MKP) capacitors engineered for low-voltage power factor correction (PFC) in industrial installations. They feature a cylindrical aluminium can with stud mounting and are supplied in single-phase and three-phase designs. Rated voltage ranges from 230 to 525 V AC and nominal output ranges from 0.5 to 30 kVAr depending on type. Typical lifetime is up to ~135,000 hours; pulse-current capability up to approx. 200·IR.

Applications

• Automatic capacitor banks
• Fixed power factor correction (e.g. motor compensation)
• Detuned (tuned-off) PFC systems
• Dynamic PFC systems

Key features

• Cylindrical aluminium can with stud mounting
• Stacked winding design
• Metalized polypropylene (MKP) dielectric
• Rated voltage: 230 … 525 V AC (type-dependent)
• Nominal output: 0.5 … 30 kVAr per capacitor (type-dependent)
• Available in single-phase and three-phase versions
• Pulse current withstand capability up to approx. 200·IR (type-dependent)

Customer benefits

• Up to 30 kVAr per capacitor in three‑phase applications
