Description

Summary

Phase Technologies has designed a groundbreaking VFD that provides full-featured speed control of the main pump and AuxPower™, an optional, independently controlled phase converter to power the entire center pivot system. Compared to a rotary phase converter, AuxPower™ provides superior voltage balance, greater efficiency and higher reliability. Reduce labor cost with one integrated panel that provides everything required for center pivot irrigation.

1LH 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 AuxPower™ outputs.  This allows the user to set the output voltage and control both the pump and pivot without concern for utility power fluctuations.

An optional Voltage doubling 1LH Series drive utilizes a single-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 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.
