Re: Heat source
- Resistive loads do not produce back EMF, only motors and other
inductive loads do that. Also there are many ways to isolate a noisy
switching circuit from the rest of you mains system. If the router
controller is significantly less expensive than this "burst-fire
controller" it should be worthwhile to try. Also does anybody
remember the "NASA motor speed controller" from ages past? It was a
common high-school project.
Personally I just use two elements.
