This speed controller has been specifically designed for low-voltage electric motors. Its main applications include the stepless speed control of DC drills, model cars, windshield wiper motors, and power tools. Due to the pulse-width modulation operating at a frequency of approximately 20 kHz, the power loss remains low even at low speeds. By using a special MOSFET transistor, the output current can be continuously adjusted from 0 to 10 A with a potentiometer, while the electronics are protected against sudden motor blockages. The adjustment range of the motor extends from complete standstill to maximum speed. With an additional potentiometer, the device offers the option to set a load-independent speed stabilization. This prevents torque and speed losses under higher loads and ensures a smooth motor operation even at low speeds. The device can also be configured for external control (external potentiometer or external voltage).
