Bought this speed controller to reduce the... flow on a 1/2 hp water pump. Slowing down the pump stopped the water from being heated up as it was being used to cool a TIG torch that has very small cooling lines. This controller worked perfectly since my motor has brushes and draws 10 amps all within specs. for this controller

Works but sruggles on the real low settings. ...Won't work with a heavy loads at the low speed settings. On non variable small drills and fans it works better. Don't use it to slow down a circular or jig saw. Over all a good tool to have.

Does the job. Great for dimming high ...wattage (up to 1500w) lights. Does. It work in some LEDs. Exact same product advertised as a dimmer from film / lighting accessory retailers goes for 2x more.

I used this rheostat to control rpm on my 15 Amp, 3750... rpm, metal chop saw. Put it on lowest setting and it cuts perfectly when I maintain soft, steady pressure, while cutting 1/4" steel plate. If "I" mess up and push too hard, or let off the trigger, and immediately apply it again, the fuse blows. This tells me it works "exactly as described", since those conditions cause a drastic rise in amperage, above the rating, blowing the fuse. The last photo shows where I pushed too fast, binding the blade, and blew the fuse. Going to restore the saw, and replace brushes. I will try again, and post results.
