As a temperature controller, I am going to use TRIAC based common fan dimmer. As I know it has faster pulses than 50Hz mains. Maybe because of this faster pulses, I hear a kind of noise from fan when the dimmer is working but not when I bypass. Question is: If I powered the dimmer in my soldering iron, does the strong pulses decrease the life of the iron coil?
Additional: what kind of devices should not powered through the dimmer?
