Feature Highlights: 1. One-Touch Sleep Mode – Just press the industrial-grade touch knob once to put the controller into sleep mode. Touch it again to wake it up and resume operation. 2. Designed for Brushed DC Motors – This speed controller is specifically made for brushed DC motors. It is not suitable for brushless DC motors and cannot be used as a voltage regulator or stabilizer. 3. Reversible Motor Direction – The motor can run forward or reverse. If it spins the wrong way, simply swap the wiring to change the direction. 4. DC Input Only – This controller must be connected to a DC power source. Do not connect it directly to AC power, as this will burn out the unit. Also, avoid reversing the positive and negative terminals to prevent damage. 5. Smooth 0%–100% Speed Adjustment – The knob allows stepless speed control. For example, when the display shows "50," it means the motor is running at 50% of its maximum speed. Product Details: This digital display PWM DC motor speed controller supports a wide voltage range of 6V–30V and offers precise, stepless speed regulation. It features a clear digital readout for real-time speed monitoring, an industrial touch knob for easy operation, and a compact design for convenient installation. Ideal for DIY projects, machinery, and equipment requiring adjustable motor speed.
