3LHE 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 without concern for utility power fluctuations.

These voltage-doubling 3LH Series drives utilize a three-phase active front end to boost the 208/240V input and generate 460V three-phase output. This innovative capability eliminates the cost of a transformer and provides significant cost reduction in submersible or long lead applications by reducing the size of down-hole motor cables.Phase Technologies now manufactures optional sine filters at a fraction of industry cost to further reduce expenses associated with long lead installations.
