3A 1203B PWM DC Motor Speed Regulator- 6V 12V 24V 28V

5A DC Motor PWM Speed Control – (3V, 6V, 12V, 24V, 35V) is a Mini Style DC Motor Speed Regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM). Precautions: DC motor governor input is DC, can not directly connect to the AC (for example home 220V AC), otherwise, it will burn! DC power supply positive and negative terminals do not reverse, otherwise, the governor may be damaged. The motor can be positive or negative when the direction of operation and expectations do not match, you can adjust the line order to change the direction. Adjust the potentiometer knob to change the governor output duty cycle, the motor speed changes. Technical Specifications: Mini DC 6-28V 3A PWM Motor Speed Controller.
