Power supply voltage: DC 5~16V Continuous current: 10A Duty cycle: 09699% Efficiency: The highest efficiency reaches 98% Output power: 90w Quiescent current: 7uA (standby state) PWM frequency: 20khz Adjustable resistor switch: turn on the switch clockwise, turn the potentiometer clockwise to accelerate the motor; Rotate the potentiometer motor counterclockwise to decelerate; Product use: The wiring between the module and the DC motor is as follows (the DC motor does not distinguish between positive and negative poles) Dimensions: length 30mm*width 26mm (without handle)*height 14mm Precautions: 1. The input of the DC motor governor is DC, and it cannot be directly connected to AC (for example: household 220V AC), otherwise it will burn out!!! 2. Do not connect the positive and negative terminals of the DC power supply in reverse, otherwise the governor may be damaged. 3. 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. 4. Adjusting the potentiometer knob can change the output duty cycle of the governor, and the motor speed can be changed.
