I have a number of tools and "appliances" where I need to control the speed more finely such as an angle grinder, router,blowers/fan, etc. They all use 120vac. I found this item that looks like it might be useful in the higher amperage devices I have. Would this work for what I am looking to do?
I alwys get confused if lowering voltage will decrease the speed or if lesser current will do it. I know if I hook some of my 12vdc fans to my 4/8/12/16v PSU the fans spins significantly faster with each increase.
