Product Description

Wenzhou Modern Completed Electric-power Equipment Co.,LTd. is the best China harmonic filter manufacturer and supplier, as a professional company, we have our own factory. Welcome to wholesale harmonic filter, passive harmonic filter, harmonic filters, harmonic filter, harmonic filtering, active power filver products from us.

With other harmonic filtering solutions, expensive and time consuming site data collection, power quality surveys and computer generated studies are usually needed. Most harmonic filters are designed to accommodate just one or a few harmonic orders.

The MODERN Active Power Filter(APF) corrects a full range of harmonic orders, and will not create a resonance condition with existing equipment.

The APF injects compensating current into the load to restore the sine wave and dramatically reduce distortion to less than 5% THD. Its high speed process cancels high frequency output current, while it determines the precise value of injected load current.The MODERN APF provides the simplest and most effective means to mitigate harmonics, reduce process-related voltage fluctuations, and improve equipment operating life and system capacity.
