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.
