I have a 240vac to 24 vdc 20A power supply which has an internal fan which is continually ON.
95% of the time the power supply draws only 5 A and could easily run without the fan.
Is there some kind of switch or device I could insert into the circuit which would activate the cooling fan only when the current draw exceeds, say 7 Amps, under that Amps the fan would not operate.
Thanks in advance
