Phase Conversion & Voltage Doubling

Cost Savings for Long Lead Applications

Phase conversion allows three-phase output from a single-phase input, giving you access to three-phase power anywhere. Voltage doubling eliminates the need for a transformer while minimizing motor lead wire size on 460V systems running on a 230V source, saving you hundreds on wire costs.

                  Output Filters

                  Output filters are necessary when motor leads exceed 50 ft. Without filters, long leads allow reflected harmonics to create dangerous voltage spikes that can exceed the insulation rating of the motor cables and windings.

                  Over time, these voltage spikes will degrade the insulation and result in motor faults. An output dV/dt (50ft to 850ft) or sine filter (50ft to 3000ft+) can be installed in the panel at the factory on most LH and DX Series systems. External filters can be placed as a stand alone on the output.

                  A filter reduces harmonics in the PWM output voltage, smoothing the waveforms to reduce vibration in the motor. Filters also reduce common mode currents in the motor windings that can discharge through motor bearings, causing pitting and premature motor failure.

                  CAUTION: Long leads between the unit and the motor with an unfiltered PWM voltage can lead to dangerous voltage rise from reflected harmonics. Very long leads, such as in deep well submersible pump applications, may require the use of a sine wave filter to remove most of the harmonics from the waveform.

                  Drive:

                  The 1LH is powered by a Phase Technologies LHX VFD

                  Enclosure:

                  Configured panels come standered with NEMA 3R all steel enclosures made in house.

                  Circuit Breaker:

                  Protect your drive with a Circuit Breaker wich comes standard with Phase units.

                  Integrated LCL:

                  Larger horsepower panels include an integrated LCL standard.

                  Output Filter:

                  Built with components to limit peak voltage, these filters are recommended with lead lengths up to and above 1,000 feet.
