Variable Frequency Drives & Digital Phase Converters

1LH Series Single-Phase To Three-Phase VFD's

1LH Series VFD’s are the only product on the market with optional AuxPower™, a revolutionary solid-state
phase converter integrated into the cabinet with the VFD.

Phase Technologies has designed a groundbreaking VFD package intended for center-pivot irrigation systems or other systems requiring a VFD and a phase converter. The 1LH with optional AuxPower™ provides full-featured speed control of the pump and an independently controlled phase converter to power the entire center pivot system. AuxPower™ provides superior voltage balance, efficiency, and reliability. Reduce labor cost with one integrated panel that provides everything needed to operate a center-pivot irrigation system.

1LH series drives have a unique active switching input module that limits harmonic distortion on the power input. These drives are IEEE 519 compliant with no additional harmonic filters 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 power fluctuations.

Voltage doubling 1LH Series drive utilizes a single-phase active front end to boost the 208/240V input to generate 460V three-phase output power. This innovative capability eliminates the cost of a transformer and provides significant cost reduction in deep-well submersible or other long lead applications by reducing the size of motor cables. Phase Technologies now manufactures optional sine wave filters providing them at a fraction of the cost of third-party suppliers, further reducing expenses associated with long lead installations.
