DC speed controls are also referred to as SCR controls or DC motor controls or DC drive. They take 120/240VAC supply voltage and convert to DC for use with 90 and 180VDC armature DC motors. Because Dart also makes digital DC speed controls we define the products below as ‘analog’ to differentiate from their digital, microprocessor-based counterparts.

The 153D-PB Series is the only DC motor speed control on the market with an integral, digital potentiometer and scalable display The 153D-25E/-200E uses the latest SCR based control design, and includes support for 240VAC supply/90VDC output, adjustable ACCEL and DECEL Discover More >
