High Efficiency Input Line Harmonic Filter Three Phase Reactor For VFD Inverter System

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).

• UL / Class H (180 °C) Insulation System: Premium thermal resistance designed for continuous, full-load operation under extreme industrial conditions.
• Effective Harmonic & Surge Suppression: Dramatically reduces high-frequency noise, current peaks, and grid-side voltage dips.
• Durable Terminal Block Design: Secure, easy-to-wire cage terminals simplify installation and reduce maintenance downtime.
• Low Loss & Low Noise: Optimized core design reduces eddy current losses, operating temperature, and acoustic hum.
• Flexible Customization: Customizable inductance (mH/μH), rated current (A), operating voltage, and physical footprints to match exact OEM specs.

Optimized for high-power industrial and energy conversion systems:
