5V-28V 12V 24V 5A PWM DC Motor Speed Control Switch Controller – DC Motor Speed Controller

          Product Dimensions ‏ : ‎ 1.18 x 1.97 x 0.59 inches

• Equipped with fuse tube to protect the speed controller from burning out that short circuit causes.
• Controls the speed of a DC motor with this controller High efficiency, high torque and low heat generation.
• With reverse polarity protection, high current protection Operating.
• Adjusting the potentiometer knob changes the governor output duty cycle and the motor speed changes.

Notes:
The input of the DC motor governor is DC power, and it is not directly connected to AC power (for example household 220V AC), otherwise, it will burn out!!!
Do not reverse the positive and negative terminals of the DC power supply, otherwise, the governor may be damaged.
The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the line sequence.
Adjusting the potentiometer knob changes the governor output duty cycle and the motor speed changes.
