Every phase converter and VFD we sell is manufactured at our headquarters in Rapid City, South Dakota. At Phase, we understand no two installations are ever exactly the same and our manufacturing process reflects that.

We treat every order like a custom order, meaning every unit that leaves our facility is hand built, fully tested, and approved for installation. Most of the components such as PCB's, wire assemblies, and enclosures are designed and built in-house. We keep our supply-chain short, and US-based whenever possible.

Because our focus is on providing customers what they need to get the job done, we are able to deliver custom solutions with off-the-shelf lead times. We strive to consistently deliver the shortest lead times in the industry.

Phase Technologies brings uncommon value to the industries we serve every day. Whether the requirements are phase conversion or a specific variable frequency drive solution, Phase Technologies' USA-manufactured power electronics deliver.
