Description

Fan speed controller based on the TC648 IC. It adjusts and holds the running speed of DC fans according to the temperature measured in the area or on the heatsink that needs cooling. It works very simply: the fan reaches full speed (100% duty cycle) when the temperature goes above 45°C, runs slowly (42% duty cycle) when the temperature reaches 30°C, and stops automatically when the temperature drops below 20°C. Supply voltage between 12V and 18V.
Technical specifications
  • Fan at low speed (42% duty cycle): when the temperature reaches 30°C
  • Maximum fan speed (100% duty cycle): when the temperature goes above 45°C
