Two-way PWM controller DORN 63120.

The controller is designed to control the speed of DC motors (with permanent magnets or induction motors) in both directions, for example in electric vehicles, karts, machine tools, or in reels for RC models. The power supply voltage of the controller can range from 12 to 63 V, load current up to 120 A. A fan for additional cooling can be purchased from the controller, which can increase the load current to 160 A. The speed and direction of rotation are either controlled only by a potentiometer or by a voltage of 0 to 5 V) or by a RC signal, or by the potentiometer (voltage) can only be controlled by the speed and direction of rotation by the switch. The controller can inhibit the motor by recovering energy back into the battery or countercurrent. The user can set up control mode, current limit, minimum supply voltage, acceleration, deceleration, maximum braking power (recuperative or countercurrent), individual control point boundaries and maximum speed in either direction. The controller has built-in thermal and surge protection.
