    AccuSine PFV+

    The Schneider Electric solution for electronic reactive current compensation for specific and high performance solutions.

    AccuSine PFV+ is a very simple and effective means to eliminate leading or lagging power factor, reduce voltage fluctuations enhance equipment operating life, and improve system power capacity. AccuSine PFV+ offers many features in one package that others require multiple models to accomplish. Power Factor correction with AccuSine PFV+ is worry-free and without the risk of resonance.

    AccuSine PFV+
    • Features

      AccuSine PVF+ can be operated as a displacement power factor correction and/or load balancing device.

      Technical Data
      Standard RMS output current ratings
      • 60 A, 120 A, 200 A, 300 A - 380 V AC to 480 V AC

      • IP00, IP20, IP31, IP54, UL Type 2, UL Type 12




      • Flexible and scalable
      • Peace of mind:
        • Worry-free power factor correction without the risk of resonance
      • Simple installation and ease of expansion
      • Flexible parallel operation modes for multi-unit installations 
      • Current transformers can be installed on the incoming mains (source sense) or on the feeders to the loads (load sense) for maximum installation flexibility  


      • Stop voltage sags and flicker due to load current fluctuations (VAR compensation): Ball mills, shredders, arc welders, arc furnaces, hard to start AC motors, and more.
      • Correction of leading power factors in data centers to allow back-up generators to operate.
      • High speed power factor correction where traditional capacitor banks are unable to track loads.
      • For larger applications AccuSine PFV can be combined with a capacitor bank to reduce the system cost. AccuSine PFV can either add or subtract to the capacitor bank output to achieve an high speed reactive compensation system with infinite resolution.
