Product overviewBased on metallized polypropylene (MKP) technology with stacked windings, DeltaCap™ X Black Premium capacitors are designed for low-voltage power factor correction (PFC) in demanding industrial environments. The compact black cylindrical aluminum can with stud provides a selective output and a wide rated voltage range for three-phase PFC applications.
Applications- Automatic PFC banks
- Fixed compensation (e.g. motor compensation)
- Dynamic PFC
- Tuned and detuned PFC systems
Features- Compact black cylindrical aluminum can with stud for space-efficient panels
- Metallized polypropylene (MKP) with stacked windings
- Reduced mounting and connection time
- Rated voltage range: 440 … 850 V AC
- Output range: 20 … 44 kvar (50 Hz)
Customer benefitsCosts- Lower system cost through higher packing density and compact cabinet footprint
Electrical- Designed for three-phase installations
- Very long life expectancy: up to 300,000 h at temperature class -40/55
- High inrush current withstand capability (up to 500 · I_R)
Mechanical and maintenance- Reduced mounting costs; easy installation and connection
- Compact volume for dense cabinet layouts
- Maintenance-free in normal operation (except recommended periodic checks)
- Mounting positions: upright or horizontal
Safety- Self-healing dielectric
- Overpressure disconnector
- Isolated terminal (IP20)
- Ceramic discharge resistor pre-mounted
