Description

Summary

1LHS 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.

1LHS Series drives utilize a single-phase active front end to convert the 460/480V single-phase input and generate 460/480V three-phase output. This innovative capability eliminates the cost of a phase converter and provides significant cost reduction by not having to derate the drive. Phase Technologies now manufactures optional integrated dv/dt and sine filters at a fraction of industry cost to further reduce expenses associated with long lead installations.
