What would you believe it's the best approach to control the following Delta fans with Arduino?
2 of PFR1212DHE-F00 (12V - 3.70A - 44.4W)
1 of AFB1212HH-F00 (12V - 0.33A - 3.96W)
There is no PWM, there is only a third wire for tachometer.
The power source can be a Molex input for an ATX power supply or have it's own external power supply.
I'm asking because I've been reading a lot about this and I'm not sure how to give it a solution, I'm a decent programmer but I lack knowledge about electricity. I'm still kind of confused about MOSFETs, Mean Well LED dimmers, IRF520, etc. Not sure what to use.
Help would be appreciated, thank you.
