Phase Technologies designs and manufactures the circuit boards, magnetics, heatsinks, the complete drive and the enclosure around it, all in Rapid City, SD. For panel shops and integrators, we supply configured panels at wholesale pricing, ready for your shop to finish. For OEMs, we provide full custom engineering and production-volume manufacturing under your brand, so you can grow your product line without building a factory.
