AccuSine PFV
  • Features

    • Provides instantaneous reactive power for displacement power factor correction of either lagging (inductive) or leading (capacitive) power factors
    • Can be operated as a displacement power factor correction and/or load balancing device

          Technical data

    • Network voltage: 208-480 VAC, up to 35 kV with transformers
    • Frequency: 50/60 Hz +/- 3 Hz
    • Ultra fast response at < 1 cycle
    • Ambient temperature: 0° to 40°C, derate 2% per degree C up to 50°C
    • Contamination levels (IEC 60721-3-3)
    • Altitude: 0 to 1000m (3300ft) above sea level - over 1000m derate 1% for each additional 100m
    • Product standards: UL, cUL, CSA, ABS, C-Tick, CE marked models available
    • Humidity: up to 95%, non condensing
    • HMI Display: Touchpad display with graphics
    • Enclosure: N1, UL Type 12, IP30, IP54, CH (Chassis)
    • Communication: Four dry (voltage free) contacts to monitor status from remote location; Modbus TCP/IP or Ethernet IP



    Benefits

    • Flexible and scalable.
    • Simple installation and ease of expansion - for parallel operation, each unit functions independently with only current transformer and communication interconnections (no power interconnections).
    • 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.
