AC Motor Variable Speed Controller & Fan Speed Regulator - 15A 110V

My fan has only ON and OFF. Putting this in-line makes it a variable speed fan, with very fine control. I'm very happy with this. When my fan is ON, the force is too much for most uses. Now, I can adjust it to what I need.

GREAT!

Cheap, for sure. And sorta kinda actually does control motor speed more or less. Voltage display is showing pretty random values. Right now, I have a motor running, maybe, at about 50% of output speed and the display is showing 162V (plugged into a standard 110v outlet). If I change the motor speed? Display will jump around between 20V and 190V. But, yeah, it sorta kinda mostly does actually work. 1 star if you were expecting a solid variac style speed controller. I give it 4 stars because I got exactly what I expected; a shoddily made, works by coincidence, motor speed controller whose voltage display might as well be a random number.

Used mine to slow down my floor fan

Bought this item on 29 Feb 2024 to slow down the speed of a small muffin fan that provides auxiliary cooling air to the electronic audio components inside a large enclosed stereo cabinet. See attached image. The reason I selected this AC controller was because there is a video on the Amazon site showing this device actually running a muffin fan that looks just like mine. See attached image. The first unit I ordered was partially defective the first time I turned it on. When connected to my muffin fan, the red digital voltage display remained at 000 no matter what the voltage control was set to. The display is supposed to change and give the output voltage value as the dial is rotated. The actual output voltage changed by rotating the dial, but no matter what the dial was set to, the display remained at 000 all the time. I returned the unit for a replacement. The second unit arrived in 2 days The red digital voltage display worked correctly the first time I tested this second unit with a 100w light bulb as the load. After I turned the unit off and back on again the digital readout remained at 000 no matter what the voltage control was set to. As before, the actual output voltage changed by rotating the dial, but no matter what the dial was set to, the display continued to read 000 all the time. A previous reviewer mention he also received a defective unit. He found a disconnect wire inside the box and, being electrically handy, soldered it back in place. He said this could have been an electrocution hazard for anyone not skilled enough to fix it. Based on this experience, I immediately returned the second unit for a refund. Buyer beware !!

I use it for a Panasonic adjustable speed wand vibrator to slow it down. The wand, while adjustable, still runs too fast for my neck. This controller slows it down enough to make it usable for me.

I bought this because I have a pedestal fan I bought last week, and even on the lowest speed it sounds like a 747 revving for takeoff. This device came an hour ago; smaller and lighter than I expected--probably because back in the 70's I worked in a chemistry lab, and we used devices called Variacs (I think) that did the same thing, but weighed probably four times as much. The critter plugged into my extension cord, and my fan plugged into it, and I turned it on, with the knob set to zero. As expected, nothing happened till I turned it up to about 15 out of 24, and then the fan slowly began to revolve. I nudged the control higher, and found that about 18/24 gave me a satisfactory combination of speed and noise. So--I am pleased. In the no-fan season, I'll likely use this to slow down a grinder that currently has only one speed; maybe some other gadgets in the shop or barn. Obviously I can't say anything yet about its durability; but so far, it rates a 5.

Worked OK as a fan controller for just about two years. Then died.

Très solide et facile d'utilisation.

Un moteur

It arrived but wouldnt control the voltage so I returned it. Must have gotten a defective unit.
