Features: 1.Can support AC and DC input. Non-existent power supply polarity problems. 2.Ultra-high voltage scope. support 12-160VDC Input. support 9-110VAC input. 3.Large radiator with mounting holes. 4.Ultra-high-power control. Max 10A current. 5.Except the board inside a PWM speed control, can also support an external PWM signal input speed control, external PWM input requirements: level 3.5-12V VPP, the frequency of 1K-10KHZ, in particular apply in MCH3 spindle speed control. 6. A wide range of support motor. Basic right into the letter drive of the market all the DC motor speed control. As long as the DC resistance of the motor is greater than 2 Ohms DC resistance can. Note in particular that this drive can not be less than the DC resistance of 2 Ohm DC motor speed control. 7.Equipped with a fuse protection and better performance. 8.The power indicator, and more convenient to use. Application: Driven from 5V to 110V DC motor, DC motor speed control. Such as equipment of DC pumps, fans, engraving machine，spindle speed of the DC motor for precise control. Package List: 1 * speed controler
