LHX- Low Harmonic Drive

Low Harmonic Phase Converting, Voltage Doubling, 240V /460V Inputs

Our LHX model variable frequency drive (VFD) featuring low harmonic technology for improved power quality, offers efficient phase conversion, enabling single-phase to three-phase power transformation, and includes voltage doubling capabilities to boost output voltage. 

This VFD is designed to reduce harmonic distortion, making it ideal for applications requiring enhanced energy efficiency and reliable operation in both industrial and commercial environments.

Overview

Class-leading low-harmonic VFD’s with revolutionary features such as a compact, integrated design and voltage-doubling. No need for an external harmonic filter on the input.

LHX Series drives have an active switching input module that limits harmonic distortion on the power input. These drives are IEEE-519 compliant with no additional harmonic filters required. The active front end also provides the added benefit of power conditioning for the VFD. This allows the user to set and maintain output voltage even in the presence of weak utility voltage.
