Hi,
I have a MKS GEN L 1.0 Board that has a regulated 2 pin FAN output on a 4.5A onboard Mosfet. Most probably generating a PWM signal to regulate.
I happen to have some powerful 12V Fans lying arround that i want to use.
3 ways sprang to my mind:
1) I connect 2 12V Fans in series, but thats dangerous and I dont know if the board can handle the addtional stress so I rather not do that.
2) I use some kind of voltage regulator between board and fan, but I do not know which one (linear or switching) or if I can regulate a PWM signal at all this way... would a 50% fan speed not result in 12V getting regulated to 12V thus giving me 100% fan speed? Or can I actually regulate every single pulse down to 12V?
3) I use a MOSFET that is PWM compatible to work with the 24V PWM as input and connect a secondary true 12V power supply to actually power the fan. I like this method best since it relieves the MKS board from stress...
Since i gathered all my electronics knowledge from the internet, I am not sure if all (any^^) of those methods will actually work.
Can you please help me?
regards
Martin
