About this item

  • This variable speed motor controller is perfect for bench testing, experimentation, industrial applications, and DIY projects, offering precise control over fan speed and voltage regulation.
  • The maximum power of this voltage regulator is 4000W,with AC 120-220V input and adjustable voltage output (0-220V), Rated current is 9A, can withstand a maximum current of 18A.
  • This motor speed controller is equipped with a new bi-directional high power SCR inside.You can easily control the speed of your motor to your desired level using the rheostat.
  • The output voltage of the product is a virtual voltage when there is no load. When a load (20W or more) is connected, the actual output voltage value is shown on the display.
  • Note: Max power limit is 1500W for inductive loads (fans, routers, soldering irons, small motors) and 4000W for resistive loads (kettles, stoves, tungsten lamps ect).



Product Description

Electric Motor Speed Controller

Flame retardant metal case

Flame retardant metal case

The heat dissipation holes enhance heat dissipation, the spray paint is corrosion-resistant, the high-temperature flame-retardant and non-deformable design avoids safety hazards, and the anti-oxidation and anti-rust design improves stability and reliability.

Multifunctional industrial socket

Multifunctional industrial socket

socket adopts thickened phosphor bronze fittings and internal copper parts, ensuring large current, good contact and safety. Moreover the design of the multi-functional socket is compatible with more types of plugs.

3-core AC power cord

3-core AC power cord

The power cord plug is designed specifically for use in the United States, with a large current carrying capacity, thick wire that is not easily bent or deformed. In addition, this power cord provides safe and reliable electricity, ensuring stability and durability of the power supply.

installation hole design

installation hole design

Scientifically designed installation holes can be both horizontally placed and suspended, providing users with a more convenient way of use. This design not only ensures the ease of use and flexibility of the installation holes, but also enhances the practicality and functionality of the product.

Instructions for Use:

  1. When measuring the output voltage, the unloaded voltage is a virtual voltage. A load of 20W or more must be connected to correctly measure the output voltage.
  2. The input and output of this product are both AC power, not DC power.
  3. The maximum power of the product is 4000W, which applies only to resistive loads. The maximum power for inductive loads is 1/3 of that for resistive loads. Resistive loads include tungsten lamps, heating wires, etc., while inductive loads include series-excited motors, etc. Please do not use this product for circuit board electronic products.
  4. This product has a metal shell and must be safely grounded.

It's nice to have speed control on my bench buffer works

I bought this under the assumption it would turn a fixed speed belt sander into a variable speed. It didn't work at all for that purpose. It would slow it down a little then the motor would stall. I gave it two stars because it does what it says and lowers the voltage but is not useful for it's intended purpose. Maybe it would work better with other types of motors/applications but definitely does not work with 1x30 belt sander.

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.

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 !!

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.

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.

We purchased this to control the temperature of a branding iron for stamping lables on leather. The output of the iron was too hot at 2000 watts and we needed to lower the temperature of the iron. With this device we were able to set the input voltage of the iron to 90 volts which reduced the wattage of the iron and gave us better control over the temperature of the iron so we aren't burning the leather. Of course this device has many other uses as well such as limiting the input voltage to Neon Sign power supplys and controlling the rate of speed of electric motors. I'm sure with your inginuity you could come up with lots of other applications you might be able to use this device for.
