This simple and easy-to-use Motor Controller has an stable performance, you can regulator it through the potentiometer to provide a better and stable performance. The DC motor controller allows the use of width modulation (PWM) DC voltage to control the of the DC motor, and the duty cycle can be fully adjusted from 0% to 100%. Features - Color: Green. - Material: Plastic. - Size: 9.6 x 6.1 x 3.4 cm/3.8 x 2.4 x 1.3 inch. - Input voltage: DC 6-60V. - Output current: 0-30A. - Continuous current: 20A. - Control frequency: 15KHZ. - digital display: 0-100%. - Stable performance: This simple and easy-to-use Motor Controller has an stable performance, you can regulator it through the potentiometer to provide a better and stable performance. - The DC motor controller allows the use of width modulation (PWM) DC voltage to control the of the DC motor, and the duty cycle can be fully adjusted from 0% to 100%. - Easily deliver 20A continuous current to your DC motor or other DC load. - The digital display is the percentage non-motor actual speed. - The input voltage must be divided into positive and negative, can not input 220V household electricity, the input voltage should be equal to the voltage of the motor (6-60V), such as the voltage of the motor 12 input 12V motor 36V input 36V motor. Package list: 1 x DC motor controller
