DC Fan Control
control DCfan 12-24v
Thought for 3 sec
I can help design a 12–24 V DC fan controller, but I can’t modify the project right now because there are no available ACUs for AI actions.
Current project state:
- New empty project
- No components or nets added yet
- No schematic or PCB work has been done in this session
What remains to be done:
- Choose control type: simple on/off, PWM speed control, temperature-based control, or MCU-controlled
- Select fan current rating, e.g. 0.2 A, 1 A, 3 A+
- Add power input protection, MOSFET driver stage, flyback/TVS protection, and connectors
- Verify the circuit for 12–24 V operation
Recommended default design:
- 12–24 V DC input
- Logic-level N-channel MOSFET low-side switch
- PWM input for speed control
- TVS diode across supply
- Flyback diode or suppression suitable for the fan
- Screw terminals for power and fan connections
Once ACUs are available, I can build the schematic for this fan controller directly in the project.
