HiLetgo 2000W PWM AC Motor Speed Control Module Dimmer Speed Regulator 50-220V Adjustable Voltage Regulator

For everyone who is curious about how it works. I wired this up to a 60w incandescent light and observed the wave. This appears to he a triac controlled device, when the dial is turned down cuts the sine wave down, when it's turned up, it allows it to go up. At full speed the wave is still partially cut but only slightly, that's just because of efficiency.This works great on my CNC shop vac, and other universal motor speed controls. Works great on resistive loads like motors, light bulbs, and probably AC heaters too (depending on the type). (Does not work on led light bulbs as they function different internally).For those of you who want to use this to vary the voltage, this won't work.The rms voltage will change a little but since the sine wave is only shortened it will still hit the high voltage levels of ~169v peak unless the wave is shortened to just a tiny piece of it. When I initially tested this is was giving full voltage full duty Cycle the whole time, it wasn't until I put a resistive load on the device that it actually began working.I have several of these because for my uses they work fantastic.

I bought this little controller to slow down a 110 vac exhaust fan about 10% or so. It was very noisy.I mounted it into a single gang box and it seems like it gets hot in there so I will probably have to vent the box somehow. But it works! It works good. There are no instructions and I read some of the other reviews so I was careful wiring it up. I adjusted the on board pot and I have full range control on the main pot. I am happy with my purchase. It fixed my noisy fan for 7 bucks! Now when I turn the fan on I blip it to 100% for a second then I adjust it to about 50%. It works great!

Powering a 5.4 amp drill, at first the device was too touchy, and only worked for a very small movement of the main potentiometer; the motor would jerk and hunt if turned too far. As others have noted, this is because it lowers output RMS voltage, and is tuned for 220V, but I was using 110. Many CW turns of the small trim pot gave me full range of speed-pot adjustment, and the motor seemed happy when full CCW of the main pot gave about 78V output with the motor running. I haven't tried it under load yet, other than to hold the chuck a bit by hand. The pot is smooth and seems substantial, and requires a 9/32" (7mm) hole, with enough thread for 1/8" maximum panel thickness (although thicker than 1/16 would allow the knob to rub on the panel if seated all the way). No room between traces/components for drilling stand-off mounting holes, but the pot mounting bracket is substantial enough to mount the device that way, as long as wires are supported. A small tab protrudes next to the pot, and a 3mm hole should be drilled in the panel 9/32"OC beside the potentiometer hole for clearance, but this will also keep the device oriented by preventing it from it from turning. Screw terminals appear a bit flimsy, but tighten "well enough" for up to 12AWG stranded wire. I'll update my review as I put this into use. And I'll use caution with low speed, as airflow and motor cooling will be diminished. I'll never give a 5 star rating until a device has lasted a year, but this performs as promised so far.

Used on 16 ohm resistance coil in a NESCO Gardenmaster food dryer. The circuit board of the NESCO dryers fail after a few months of continuous use (I’ve gone through like six of them). Needed to replace NESCO’s circuit with something more reliable so that I can adjust thermal output of the coil for different applications (drying meat vs herbs, etc) without spending $150 every year. Wired this up to the coil and it tested good! Did what it was supposed to. Now I’m reassembling the dryer and rewiring this device in a project box for prolonged use.We’ll see how the HiLetGo stands the test of time. But even if it fails at the end of the season, at least it’s an inexpensive replacement part, vs buying an entirely new dryer.

I have tried this on a 720W 16" stand fan, a 65W Dehydrator and an 1100W popcorn popper, all 120V/60Hz units. It doesn't really work on any of them although the fan motor was able to get some control. I have adjusted the trim pot to each extreme and all points in between without successfully finding the spot for each device to be controlled properly. You can hear a "click" when you reach the end of travel in each direction of the trim pot. The motor or heat doesn't come on until 3/4 turn. At best I was able to find a middling of control with the motor very little with heat units. Basically it's all or nothing. I had high hopes for this unit. Maybe I received a defect, but I really don't think so. I'll update this review if the supplier wants to replace a possibly defective unit. We'll see.

Controlling a 1/4hp grinder motor. Maybe about 4 speeds possible, but the lowest are useless and have no torque - the motor stops from even slight pressure. Anything but the highest setting induces vibration in pulses. Pretty much totally useless, get a vfd if you need to control an ac motor.Pretty much what I expected, but for $6 I figured it was worth a try at least. If I switch to a dc motor it'll be nice to have for pwm input on the drive controller.

Working like a charm! Had an AC 120v fan I put in my DIY subwoofer amplifier enclosure that moved a lot of air but was a bit too noisy. This little guy lets me adjust it down to near stealth level. Very happy. Don’t forget to adjust the potentiometer.

Ne pas acheter reçu. Mais ne fonctionne pas et le fournisseur ne veut rien savoir il dit qu'ils sont testée et que c'est nous qui ne savons pas s'en servir ils nous prennent vraiment pour des tocards.aucun retour possible pour échanger et aucun remboursement super !!! Un produit défectueux de mauvaise qualité. A éviter

Did the trick on my ceiling fan that was not variable speed

It is a good product for controlling the speed of drill machines, grinders, and other similar power tools. It works well for adjusting the speed according to the requirement.”

El producto está bien permite regular el voltaje de aparatos de 220v. En mi caso se trata de un motor al que tenía que bajarle las revoluciones de 13000rpm a cerca de 5000 rpm/m. Lo he podido utilizar gracias a un regulador que lleva en el interior para bajar o subir el voltaje de entrada según lo que sea necesario. Es sencillo pero funciona. Instalarlo es fácil, dos cables de entrada y dos de salida hacia el aparato a regular.No trae instrucciones. Es frágil y hay que ir con cuidado al instalarlo. No se lo que durará pero de momento por el precio está bien. Ah, envían dos unidades. Es solo para 220-230v.

V.good product
