PWM controller, which 'dims' the output by means of PWM (pulse width modulation). With the button the duty cycle can be set between 10% and 100%, so that the speed of an engine, fan or the power of a lamp can be limited.

AOle MeulenbeltIf it is a DC brushed motor then you can reverse the polarity and it will turn the other way.
QRobinBought this module here some time ago, and only recently tried to use it with a 12v adapter, to run a 12v pc but unfortunately it didn't work ... (The fan worked without the controller by the way) Someone tips or suggestions?ViewHide 2 answers | Answer this question
AId lasapparaten serA potentiometer of 100kohm must be connected to the white 3-pin plug, without it it will not work. The black rotary knob controls the duty cycle from 10 to 100%.
ABen RaaijmakersThe requested current from the fan is too low (usually plus minus 0.25amp) The module does not respond to it. There are mini modules on the market that can have a maximum input voltage of 12 v. That does work.
QRichardCan the pwm be overruled by, for example, connecting the minuses or pluses by means of a switch? So that you have full power again for a short time?ViewHide 1 answer | Answer this question
ABen RaaijmakersNO! If you do, your module is finished!
QArieWhich power source and/or supply voltage does this circuit need exactly?ViewHide 1 answer | Answer this question
AOpencircuitThe module can be connected to a voltage source with a voltage between 12V and 40V.
