About this item

  • >【Technical Parameter】Input voltage AC 100V-120V; Output voltage AC 0-120V adjustable; Max current 15A; Rated current 10A; 4000W is the maximum power when working under a resistive load, and the inductive load is 1/3 of the resistive load.**Note: only be used for AC.
  • >【15A Overload Switch】The speed controller is equipped with an independent switch for voltage control. When the instantaneous current exceeds 15 amperes, the switch will automatically power off.
  • >【Lightweight and Safe】The controller is equipped with an ABS flame-retardant insulating shell and a socket with a protective sheet. It is light and sturdy, preventing accidental touches to protect user safety, and has excellent safety performance, Plug and Play, making it very suitable for use in homes and shops. **Note: The controller power plug must be connected to the ground wire.
  • >【LED Voltage Display】Variable speed control adopts precision pressure regulating knob for voltage regulation,through the digital display screen,show the real-time output voltage, make the machine working voltage number clearer.
  • >【Wide Application】Variable speed controller can regulate speed, temperature, voltage and light, which is suitable for US standard A and B plugs, widely used in exhaust fans, electric furnaces, angle grinders, marble machines, blowers,drills, angle grinders,etc.***Not support (such as single-phase motors, asynchronous motors, dual-value capacitor motors, water pumps, negative pressure fans, centrifugal fans, etc.)voltage regulation.

Does what it's supposed to do.

I use this for a speed controller on an attic exhaust fan and it seems to be the ticket

Does a pretty good job. Don't run at too low a speed, only > 65%.

I got this to use with a rather nice metal, shop style floor fan that just doesn't have a true "low" mode. What is it with floor fans that seem to have 3 different "high" settings?Anyway, I plugged the fan into this thing and was immediately impressed by the granularity of the adjustments. This controller can adjust the voltage to the tenths of volts and it is reflected in the fan itself. I didn't realize how much difference 0.3 volts could make in the amount of noise a regular fan makes. I suppose it has something to do with coil whine or motor resonance or some other magic but this thing has turned my loud annoying shop fan into a pleasure! There are now multiple sweet spots that I have found at different speeds for the fan, I just wish this controller had a memory function!I was worried this would get hot but so far it has stayed cool to the touch even after hours of use. This simple little controller has been a nice surprise.

The "AC Fan Speed Controller, 100V~120V 15A 4000W Motor Variable Speed Controller with Overload Protection,Electric Motor Voltage Regulator for Router Rheostat Fan" I received works pretty much as described.However, take note that for an AC fan to adequately vary its speed, voltage should be kept constant, and frequency should be varied. This controller varies voltage, not frequency. So you may experience excessive humming at certain settings.I ordered this because of the voltage display and current handling capacity. It acts a little like a variac which can help testing various products.I tried this on a laminar flow hood that is exhorting too much air flow. It did the job, but as I mentioned... it also introduced hum.It's a decent variable AC voltage controller. Worthy of recommendation imo.

I ordered this AC controller to use with my fixed-speed orbital sander that sometimes gets too aggressive, making it difficult to control. With this AC voltage controller, I was able to adjust the speed of my sander and achieve better results with a variety of sanding grits and materials.I did have one issue with the rheostat. The speed control knob rotated past the minimum and maximum settings. Upon examination, I discovered that the nut securing the rheostat to the case was loose. After removing the knob, I was able to tighten the nut firmly. After turning the rheostat to zero, I aligned the knob and reattached it simply by pressing down, thereby eliminating the problem. It would have been a better design to utilize a lock washer with the nut or a combination lock nut to keep the assembly from moving.I was planning to give this AC controller a five-star review despite the problem with the rheostat but I also spotted an issue with their marketing. It really irritates me when companies market products when they have no understanding of how to use them, or when their marketing photos are misrepresentative. If you look at the online “APPLICATION” photo, the top-left device is a BATTERY-operated drill/driver! Really?Regardless, after a little repair work, I was able to utilize the speed controller with a variety of AC voltage devices. If you have fixed-speed AC voltage hand tools, you should consider adding this product to your shop.

It regulates voltage . The electric motor I wanted to control wouldn't run under voltage.
