4 Wire 48V Fan PWM Control Possible with Arduino Mega 2560 ?

Using Arduino Programming Questions
1

I have just burned my expensive IP68 fan while making research :confused:. I just want to ask is it possible to control 4 wire PWM (48V) fan's speed with Arduino Mega 2560 R3? The PWM voltage signal has 0-5V.

The "IP68 " spec appears to relate to the design of the fan to resist dust and dirt. You need to give a link to the exact data sheet on YOUR fan.

Actually the question is not "does my fan support PWM". Because i already know that it supports the PWM and FG because it is custom made fan and the minimum technical requirements given by me. I just wonder and confusion about PWM output signal is 0-5v but my fan is 48V. I mean is it technically possible ?

Sure. Done all the time! A mosfet that will handle the 48 volts can be switched on and off by the Arduino pin and you will get a copy of the PWM at 48 volts.
