When DCI incorporated in 1990, the treadmill industry was using Industrial SCR motor control technology.

While this worked at the time, the cost and noise of these SCR controllers was prohibitive.

This pushed the industry to look to advanced technology to reduce cost, eliminate noise, and provide a more stable and precise control for treadmills.

DCI recognized this need, and worked independently to design FET Based PWM (Pulse Width Modulation) controllers. Not only did we design and sell directly into the fitness marketplace, but we also designed and patented additional safety circuitry that could not be implemented on the existing SCR controllers.

Today, DCI designs and manufactures the motor controllers used in over 50% of the treadmills in the world.
