CoEpo-APF series active power filters are connected to the power system in parallel. The system data is collected in real-time through an external sampling loop. The internal core computing chip analyzes the harmonic component data and controls the IGBT. High-frequency switching outputs a current with the same magnitude and opposite direction to the harmonic current, effectively canceling harmonics and ensuring grid stability.
High Power Density: Our APF module offers 75A or 50kvar within the compact dimension of 500*550*190mm, suitable for cabinets as small as 600mm width and depth.
Professional Structure: Features reasonable layout, reliable wiring, and isolation between control power and strong current for enhanced stability. The independent air duct design ensures sensitive components are protected.
Our APF interaction system supports both 4.3-inch built-in LCD touch screens for local management and external 7/10-inch centralized monitoring units. This allows for real-time monitoring of electrical parameters, harmonic data, and fault alarms.
A chemical plant utilizing high-power pump equipment faced severe harmonic distortion (35%) due to frequency converters. After installing our APF solution, the total harmonic distortion dropped to approximately 5%, restoring the power grid environment.
A commercial building experienced N-phase cable heating due to 3rd harmonics from LED lighting. After treatment, the N-phase current dropped from 251.4A to 17.2A, and the total harmonic distortion decreased from 47.2% to 4.6%.
