About Single Phase to 3 Phase Converter The average person's understanding of electricity goes no further than knowing when a cord gets plugged in or a switch gets thrown, the electricity starts the device — the reality is that powering your equipment is much more complicated, particularly when you are working with poly-phase equipment in a shop that only has single-phase capability. A single-phase to 3-phase converter allows you to convert power from single-phase configuration to 3-phase configuration so you can use your equipment without making expensive modifications to your workspace. While single-phase power provides all of the power you need in one current, this can produce an unbalanced load. Using a 3-phase power converter takes this single current and transforms it into alternating currents, creating a balanced load that is safer and more efficient for poly-phase equipment. Shop the vast inventory on eBay to find different single-phase to 3-phase converter options, including rotary and static converters appropriate for equipping your workspace with a wide variety of equipment.
