1LHE Series drives have a unique active switching input module that does not produce high levels of harmonic distortion. These drives are IEEE 519 compliant with no additional harmonic filter required. The active front end also provides the added benefit of power conditioning for the VFD. This allows the user to set the output voltage and control the pump without concern for utility power fluctuations.

Phase converting 1LHE Series drives utilize a single-phase active front to generate clean and balanced three-phase 460/480v output. You can even take a 208v single-phase input, and output 480v three-phase, perfect for those deep well sets where limited/dirty power is available.
