Achieving high reliability with a dedicated reactor and long-life capacitor.
The "Power Harmonic Filter" is a PHF harmonic filter for inverters that suppresses the harmonics of the inverter input current and significantly improves the current waveform. It can reduce undesirable harmonics generated by equipment within the factory to a level that easily meets harmonic suppression guidelines, thereby resolving harmonic issues in the factory power distribution system. It is suitable for harmonic suppression measures for variable speed operations such as fans, compressors, and pumps driven by inverters, as well as high-torque operations requiring overload capacity, like conveyors. 【Features】 ■ Compliance with harmonic current suppression guidelines ■ Prevention of factory troubles caused by harmonics ■ Increased usable KVA of transformers due to the suppression of harmonic currents *For more details, please download the PDF or feel free to contact us.
