Aluminum capacitor DeltaCap™

polypropylene filmmetalized polypropylene filmcylindrical

Overview
DeltaCap capacitors use proven MKP metallized polypropylene technology with stacked windings and are designed for low-voltage power factor correction (PFC) in industrial installations. The compact, cost-effective cylindrical aluminum-can design covers a wide output range and supports both single-phase and three-phase applications.

Applications

• Power factor correction (PFC)
• Automatic capacitor banks
• Fixed PFC (motor compensation)
• Tuned and detuned PFC systems

Features

• MKP technology with stacked windings
• Cylindrical aluminum can with stud connection
• Voltage range: 230 … 525 V AC
• Output range: 0.5 … 33 kvar
