Specifications:

Features: Made with a PCB of: 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, high current operation.

Adjusting the potentiometer knob changes the output duty cycle of the regulator and the motor speed. Specification: Item Type: PWM Motor Speed Control Switch Material: Electronic Components Output Current: 0.5A Output Power: 90W (maximum) Quiescent Current: 7uA (standby state) PWM Duty Cycle: 1%-100% PWM Frequency: 20kHz Weight: Approx. 16g Package List: 1 x Motor Speed Controller Switch Notes: Do not reverse the positive and negative terminals of the DC power supply, otherwise the regulator may be damaged. The motor can be either positive or negative. If the direction of rotation is not as expected, the direction can be reversed.
