Product information:

Model: PWM DC motor governor
Operating voltage: DC4.5V-35V
Output current: 0-5A
Output power: 90W()
Static current: 7u A (standby state)
PWM duty cycle: 1%-
PWM frequency: 20khz
Dimensions: L 30MMx W 26MM (excluding handle) x H 14MM

Note:
Dc motor governor input is direct current, not directly connected to AC (for example: household 220V AC), otherwise it will burn out!!!
Do not reverse connect the positive and negative terminals of DC power supply, otherwise the governor may be damaged.
The motor can not be positive or negative, and can change direction by adjusting the line sequence when the running direction is not consistent with the expectation.
Adjusting potentiometer knob can change the governor output duty ratio, motor speed change.
