DC motor controller, adjustable potentiometer, LED dimmer, reverse polarity protection, PWM for electrical

Features: 1. Made with a high-quality printed circuit board that ensures a longer lifespan. 2. Equipped with a fuse tube to protect the speed controller from burnout caused by short circuits. 3. Controls the speed of a DC motor with this controller. High efficiency, high torque, and low heat generation. 4. With reverse polarity protection and overcurrent protection. 5. Adjusting the potentiometer knob changes the output duty cycle of the controller, thus changing the motor speed. Specifications: Features: Made with a high-quality printed circuit board that ensures a longer lifespan. Equipped with a fuse tube to protect the speed controller from short-circuit damage. Controls the speed of a DC motor with this controller. High efficiency, high torque, and low heat generation. With reverse polarity protection and high operating current protection. Adjusting the potentiometer knob changes the output duty cycle of the controller, thus changing the motor speed. Specification: Item Type: PWM Motor Speed Control Switch Material: Electronic Components Operating Voltage: DC 4.5V-28V Output Current: 0-5A Output Power: 90W (maximum) Quiescent Current: 7µA (standby state) 16g Package List: 1 x Motor Speed Controller Switch Notes: The DC motor controller input is a DC power supply and should not be directly connected to an AC power supply (e.g., household 220V AC), otherwise it will burn out!!! Do not reverse the positive and negative terminals of the DC power supply, or the controller may be damaged. The motor can be either forward or reverse. If the direction of rotation is not as expected, the direction can be changed by adjusting the wiring sequence. Adjusting the potentiometer knob changes the controller's output duty cycle and the motor speed.
