AccuSine PCSn Active Harmonic Filter (AHF) Part of the AccuSine+ family, the AccuSine PCSn is the ideal solution for harmonic mitigation in commercial buildings, light industry, and other less-harsh environments. In addition to 3-phase mitigation, AccuSine PCSn can compensate for neutral harmonic currents, typically present in building and commercial environments where single-phase non-linear loads are present. • Configurable: One solution for multiple needs, AccuSine PCSn can be configured for Harmonic Mitigation + PF Improvement + Mains Load Balancing. • Best-in-class performance to reduce THDi < 3%: Built on award winning AccuSine+ technology, this guarantees a harmonic-free system, improving system reliability, and increasing operational efficiency and uptime. • Power Factor (cosφ), THDi, and THDv setpoint features provide system-level visibility and control, ensuring that you comply with utility code, and that your system is running at optimal efficiency. • Harmonic mitigation eliminates harmonic current in the neutral. In a 3-phase system, unbalanced loads introduce a current in the neutral. Applying the mains load balancing function reduces the neutral current to zero, resulting in a perfectly stable system. • Smart commissioning: Automatic CT polarity detection and correction, intelligent paralleling algorithm saves you time through unit self-identification, system view allows commissioning of the entire system from any one unit. • Simple Scalability: Add more AccuSine modules as your harmonic mitigation needs change with your load requirements, easily integrating new modules through intelligent paralleling capabilities. • With conventional power quality solutions you need high capital investment, incur large operating costs and may find it difficult to comply with IEEE 519 guidelines. The PCSn is the perfect alternative to conventional solutions like Harmonic Mitigation Transformers, Isolation Transformers, Passive Filters, Dual winding transformers. • AccuSine PCSn integrates with EcoStruxure™ Power’s edge control power management and control software and analytics services that scale to your demands AccuSine PCSn Sizing: For proper sizing of AccuSine units, contact your local Schneider Electric representative or visit us at https://www.se.com/us/powerandenergy. To expedite the product selection process, please have a single line diagram and/or details of the application including sizes of transformers, non-linear and linear loads, and any existing filters and capacitors. and adapt to your needs. • CEand C UL US certified.
