Description

Summary

3LH 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 and Aux Power outputs. This allows the user to set the output voltage and control both the pump and pivot without concern for utility power fluctuations.

Phase Technologies now manufactures optional sine filters at a fraction of industry cost to further reduce expenses associated with long lead installations.

Industries served: Wells Pumps, Irrigation Pumps, Motor Control
