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

    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 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.
