LHX SERIES

Low Harmonic | Active Front End | Variable Frequency Drive

5 - 500 HP | 230 V, 460 V, and Voltage Doubling | NEMA 1 Standard

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.
