High-Efficiency Power Quality Solution for Inverters, PV Inverters & Industrial Drives
The Three-Phase Line Reactor (EI200 Series) is engineered to filter voltage spikes, suppress harmonic interference, and protect sensitive power electronics in demanding industrial environments. Built with high-grade silicon steel laminations, copper-clad or pure copper windings, and heavy-duty terminal blocks, it significantly improves power factor, mitigates total harmonic distortion (THD), and extends the operational lifespan of your downstream equipment (such as VFDs, solar inverters, and EV chargers).
