    AccuSine PCS+

    The Schneider Electric solution for active harmonic filtering in industrial installations.

    AccuSine PCS+ is a flexible, high performance, cost-effective solution for stabilizing electrical networks by providing harmonic mitigation, power factor correction and load balancing.

    AccuSine PCS+
    • Features

       

      • A complete solution for harmonic filtering that meets every harmonic standard around the world.
      • Can be operated as a displacement power factor correction and load balancing device independent of or in conjunction with harmonic mitigation.

      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

      Number of phases

      • 3-phase, with or without neutral

      Spectrum cancellation

      • 2nd to 51st, discrete; fully selectable per harmonic order (amplitude and on/off)

      Harmonic Attenuation

      • Closed Loop: < 3 % THD(i); max 20:1 THD(i) reduction with load harmonic current above 50 % of AccuSine PCS+ rating
      • Open Loop: < 5 % TDD

      Benefits

       Flexible and scalable:

        • All types of harmonic producing loads
        • Single load, bus or global site filtering
        • Compatible with future load changes
      • Easy sizing and independent of system impedance
      • Simple selection online tool
      • 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
      • Peace of mind:
        • Achieves compliance with any harmonic standard anywhere around the world when sized correctly
        • Compatible with generator sources - off loads generators of reactive and harmonic current demands to extend life and ensure proper operation of generators
        • Compatible with UPS sources: relieves UPS of reactive and harmonic current demands to ensure proper operation of UPS
        • Ensures energy efficiency by optimising transformer and cable capacities; reduces utility power factor penalties; and saves the cost of generation and transmission of reactive and harmonic current (non active currents)
        • Maximises up time when used for harmonic and/or power factor correction.

      Applications

       

      • Anywhere nonlinear loads are present: water/wastewater facilities, HVAC systems, oil & gas platforms, petrochemical plants, port cranes, mining, pharmaceuticals, pulp & paper, automotive plants, all-electric ships, wind mill and solar farms, steel mills, plastic extrusion plants, and more.
      • 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.
