Hello,

In order to operate a device with huge current draw (i.e: radiator fans) with a PWM signal from the ECU auxiliary outputs (for speed variations), what should be used ? I guess a relay won't be able to do the job since the frequency of a relay is not that high I suppose ?

Solid State Relay, or Dual-Half Bridge.
