Quiescent current: 7ua (standby)

PWM duty cycle: 1% - 100%

Pulse width modulation frequency: 20KHz

Size: 30mm x26mm x14mm (without handle)

Matters needing attention:

The input of DC motor governor is DC and cannot be directly connected to AC (e.g. household 220V AC), otherwise it will burn out!

The positive and negative terminals of DC power supply must not be reversed, otherwise the governor may be damaged.

The motor can be positive or negative. When the running direction does not match the expectation, the line sequence can be adjusted to change the direction.

Adjust the potentiometer knob to change the duty cycle of the governor output and the motor speed.

Package includes:

1 PWM DC motor speed controller
