The voltage to pulse width modulation (PWM) can transform analog voltage into 0-100% PWM duty cycle output. The converted voltage range can be selected (using jumper) either to be from 0 to 5V or 0 to 10V. For example, if the selected range is 0 to 10v, then 10V will correspond to 100% duty cycle, 9V correspond to 90% duty cycle and so on. The precision of the converted value can be fine- tuned using the potentiometer.
