Have a Class 2 transformer:
Input: 120V 60Hz 25W
Output: 12VDC 1000mA
And a DC brushless fan rated at:
DV12V 0.48A
For this project I would like to use a on/off rotary potentiometer to adjust the fan speed from off to barely moving to fast (wide open) over the range of the potentiometer with out over loading the fan or power supply. Can someone give a me suggested ohm rating that I should use on the potentiometer? If the components that I have selected are not correct for my project please feel free to suggest different components that would be better suited.
Thanks in advance for your help,
Carl
