All the FAB, RAF and Pluto series screwdrivers work in combination with a control unit acting as an AC to DC transformer and torque controller. The electronic control circuit cuts the manufacturers of power supply to the motor as soon as the pre-set torque has been reached.
Heavy duty construction for industrial environment with as many options as you can name (soft start, adjustable speed, torque signal,screw depth control, number of cycles control, remote start, remote reverse, multiple outputs, etc.) position these controllers at the top of their class.
