AccuSine PFV+

Electronic reactive current compensation for specific and high performance solutions.

Part of PowerLogic

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
    • 47 A, 94 A, 157 A, 235 A - 480-600 V AC
    • 40 A, 80 A, 133 A, 200 A - 600-690 V AC

    Nominal voltage

    • 380-480 V AC; +10%/-15%
    • 480-600 V AC; +10%/-15%
    • 600-690 V AC; +10%/-15%

    Up to 35kV with external transformers.

    Nominal Frequency

    • 50/60 Hz, ±3 % auto sensing

    Power factor correction

    • Optimized unity PF, Leading (capacitive) or lagging (inductive) power factor (Cos f) to target.

    Mains current balancing

    • Negative sequence current injected to balance fundamental current on the mains due to load imbalance (inherently corrects displacement PF (Cos φ)).

    Control response time

    • 25 μs

    Reactive correction time

    • 1/4 cycle

    Operating Temperature 

    • 60 A, 120 A & 200 A: IP00, IP20, UL Type Open, & UL Type 1 configurations -0 °C to 45 °C
    • All others 0 °C to 40 °C
    • Derate 2 % per degree °C to 50 °C

    Relative humidity

    • 0-95 %, noncondensing

    Operating Altitude

    • 1000 m (derate 1 %/100 m above)

    Standards compliance/certification

    • cULus (UL508 , CSA 22.2 No. 14)
    • CE Certified, ABS, Lloyds, other local standards

    Display

    • 145 mm QVGA TFT 7-color touchscreen

    HMI (Magelis STU)

    • Plain language output (no cryptic codes)

    Protection (enclosure)

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

     



    Benefits

    • 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  

    Applications

    • 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.
