| Harmonic distortion, causing system malfunction
AccuSine PSCn, an active harmonic solution
| Reduce THDi to less than 3% with AccuSine+ technology

Schneider Electric launched the active harmonic filter 'AccuSine PCSn' on the 14th.
AccuSine PSCn is a power quality product within Schneider Electric's integrated architecture platform, EcoStruxure Power. It is specifically designed to mitigate harmonics and reduce voltage fluctuations in commercial buildings and light industrial applications.

Harmonic filters are essential to prevent harmonic distortion, which can lead to system malfunctions and equipment downtime, such as overcurrent, equipment failure and noise, and control device errors.

Schneider Electric's AccuSine PSCn is a scalable and flexible, high-performance active harmonic solution. It provides reliability and efficiency to power systems, extending equipment life and uptime while dramatically improving energy efficiency.

AccuSine PSCn features active harmonic mitigation, reducing Total Harmonic Current Distortion (THDi) to less than 3%. Additionally, it is built on AccuSine+ technology to eliminate harmonics from the system, improve system reliability, and increase operational efficiency and uptime.

It also features Power Factor Correction (PFC) functionality. Power factor (cos φ), THDi, and THDv setpoints provide system-level visibility and control, ensuring compliance with utility regulations and optimal system efficiency.

Mains load balancing is also a feature. While harmonic mitigation can eliminate harmonic currents flowing in the neutral line, current still flows in the neutral line in three-phase systems with single-phase loads. Applying mains load balancing reduces neutral current to zero, ensuring a safe system.

Additionally, its modular design facilitates scalability. It can be expanded to accommodate evolving power systems, and its intelligent parallel connection function facilitates integration. Furthermore, this product's unique algorithm reduces installation time, and the System View allows for complete system commissioning from any device.

“Harmonic currents are a significant issue in power networks, especially as nonlinear loads increase,” said Nicolas Larue, Global Service Manager for Active PFC at Schneider Electric. “Harmonic currents can cause equipment malfunctions, downtime, and significant increases in operating costs.”

“Schneider Electric’s AccuSign PCSn is a new solution based on the AccuSign+ platform and is optimized for less harsh environments such as commercial buildings and light industry,” he continued.
