Infofilter Series

An active harmonic filter measures the harmonic current generated by nonlinear loads and eliminates harmonics by creating a harmonic current with the same amplitude but in opposite phase. It eliminates load harmonic current and provides sinusoidal current within the system.

• Active harmonic filtering (between 2nd and 51st harmonics)
• Ability to correct unbalanced load currents, suppress neutral currents,
• Correction of neutral-ground voltage distortions caused by harmonics.
• Programmable inductive and capacitive compensation,
• Full-time DSP control system,
• Suitable for 3-phase 3-wire / 4-wire systems
• Simultaneously regulates 12 selectable harmonics,
• Modular design, very easy capacity increase,
• Wide capacity range from 35A to 960A,
• User-friendly analyzer control panel ,
• Closed/open loop control,
• Easy maintenance thanks to rack/wall-mounted modules,
• Connects in parallel to the system, no overload issues,
• Can be commissioned without interruption.
