The Dual SCR drive provides the power of two drives in one! Now with one DC drive, you can conrol two different DC motors either independently or in a ratio mode. In independent mode, each side of
the drive can be controlled differently with different trimmer pot settings and different speeds. In a ratio mode, one speed potentiometer sets the main speed while the other one determines the
ratio of the speeds between the motors. In this mode, the drive replaces two single drives and possibly a seperate master/follower card resulting in extreme cost and panel space savings!
