B25667C4277A375概述

    Product Introduction
    Film Capacitors – Power Factor Correction
    PhaseCap Premium capacitors are designed specifically for power factor correction (PFC) in electrical networks. These capacitors come in two series: MKK440-D-16.7-01 and MKK480-D-20-01, and are ideal for industrial applications where high reliability and efficiency are essential. They feature self-healing technology and are optimized for three-phase delta-connected systems.

    Product Features and Advantages
    The PhaseCap Premium capacitors offer several unique features:
    - Self-Healing Technology: Ensures continuous operation even after minor dielectric breakdowns.
    - Delta Connection: Suitable for three-phase systems, enhancing efficiency.
    - Natural/Air Cooling: Reduces cooling costs and increases lifespan.
    - Triple Safety System: Includes an overpressure disconnector for enhanced safety.
    These capacitors are particularly advantageous in environments requiring stable power factor correction and efficient energy management.
    Application Case Studies and Usage Suggestions
    Applications:
    - Industrial power distribution systems
    - Factory automation equipment
    - Renewable energy systems
    Usage Suggestions:
    - Ensure proper installation with at least 12 mm clearance above the capacitor.
    - Regularly monitor capacitor temperatures to prevent overheating.
    - Consider installing additional reactors if non-linear loads increase significantly.
    Compatibility and Support
    These capacitors are compatible with various industrial control systems and adhere to international standards such as IEC 60831-1/2 and UL 810. EPCOS provides comprehensive support, including detailed installation manuals and ongoing maintenance guidance.
    Common Issues and Solutions
    | Issue | Solution |

    | Excessive capacitor temperature | Increase ventilation or reduce load |
    | Overcurrent | Install HRC fuses or MCCBs |
    | Phase opposition upon re-switching | Implement adequate discharge mechanisms |
    Conclusion and Recommendation
    The PhaseCap Premium capacitors represent a robust solution for power factor correction in industrial settings. Their advanced self-healing technology, excellent thermal performance, and reliable safety mechanisms make them a top choice for demanding applications.
