Analog DC Speed Controls

Analog DC speed controls are also referred to as SCR controls or DC motor speed controls.  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.
