The default PWM signal level is 5V, the signal frequency is above 1KHZ, and the load capacity is above 0.5MA. 2. The 5V level does not need a series resistor to be input in the PWM port, the 10V level PWM is input from the 0?10V port or the series 10K resistor is input in the PWM port, the 12V level series 3.9K resistor is input from the 0?10V port or the series 13.7K resistor input in PWM port, the 24V level string 16.8K resistor input from 0?10V port or string 27K resistor input in PWM port. 3. The product is a DC motor speed controller, which can only be used for DC motor speed control, non switching power supply, and cannot be used for power supply of other equipment. 1 x DC Motor Governor 1 x Knob
