PHF is kind of low-pass harmonic filter to help improving harmonic currents, so that the total THDI and THDV can meet the limits of IEEE519,and the power factor can reach above 0.95 at 100% loading. There is no resonance between PHF and system power. The input capacity can be switching in different groups according to the load request, to avoid the over compensation and under compensation of power factor.

Instant IEEE 519 Compliance: 

LTEC passive harmonic filters help reduce your total harmonic current distortion (THDi) to below 5%, meeting the strictest power quality requirements.

Intelligent Power Factor Correction: 

Even under full load conditions, these filters optimize your power factor to over 95%, reducing reactive power penalties and freeing up system capacity.

Modular Versatility: 

Our harmonic filters feature a modular design with IP00 (open type) models for easy integration into cabinets, and also offer enclosures with IP20 to IP54 protection ratings to suit more demanding industrial environments.

Energy Efficiency (>99%):  

Utilizing precision design with iron cores and high-purity copper windings, these filters ensure extremely low insertion loss and heat dissipation, providing ultra-high energy efficiency.
