This is Alltrax's newest line of regen (shunt wound) separately excited motor controllers. It offers many advantages over their older DCX line. Includes a fuse, stainless steel mounting bolts, flexi-mount adapter plate, instruction manual. NOTE: This unit has connections and programming for a compatible Yamaha G19 stock electrical system. If you don't have a stock motor please contact us the same day as your order with your motor model number and voltage so we can reprogram the controller before it ships.
