Gemini Controls LLC, is a Woman Owned Small Business located in Cedarburg Wisconsin (USA), which was started in 1968. Gemini personnel have designed and manufactured electronic products for small, medium and large companies, including Rockwell, Eaton, Reflex, Sumitomo, Buehler, Tab Products, American Rotary, E.J. Cady, Spirit Fitness, Jog-A Dog, and many more. Design expertise is focused on power conversion applications, such as DC adjustable speed drives, power supplies and SCR power controllers. Gemini pulse width modulated (PWM) DC drives are designed to operate with brush-type Permanent Magnet DC motors. The evolution of Gemini's PWM drives has led to numerous advantages over SCR based and other PWM drives, including, smooth operation, audibly quiet and less line current consumption at low speeds. Gemini SCR DC drives are designed to operate brush-type Permanent Magnet DC motors featuring smooth operation due to high speed switching and exclusive motor inductance compensation which provides the fastest response to load and speed changes. ln the past we have supplied controls to high volume treadmill companies. We still manufacture controls for various treadmill companies and also sell replacement controls to repair shops as well as repairing controllers from treadmills. Some of the companies we have supplied were, Amadas, Bodyguard, DP, Hebb Trimline, Kurt, SST Spectrum, Spirit, Trotter/Cybex, as well as United Ventures Fitness. Our control can also be substituted for other manufacturers as well.
