AC Variable Speed Controller, 120V~220V 15A 4000W SCR Voltage Controller for Router Fan Electric Motor Rheostat

Bought this for use with a 240v griddle from the EU. The griddle has no temp control and 220v was too hot. Using this controller, we were able to adjust the voltage and thus the griddle temperature to just the right degree, which is about 185v for our task. I wasn't sure if this would work, but it works very well.

nice equipment, i misread the voltage output.

We purchased this AC variable speed controller for use with a motor that powers our waterfall, and it works exceptionally well! The controller allows for smooth and precise adjustments, providing great flexibility to control the water flow exactly as we want. The performance has been consistent, and it's made a noticeable difference in the operation of our waterfall.One thing to note, however, is that the unit is not waterproof. While this is not a dealbreaker for us, having a waterproof option would be a fantastic addition for outdoor or high-moisture settings. Overall, we're very pleased with the functionality and reliability of this product. Highly recommended for those needing motor speed control!

Got this and was surprised at how lightweight it is. Weight-wise, it feels like the controller is empty, and feels like it was made very cheaply. Was skeptical, but plugged it in to run a large shop fan. This fan has 2 speeds - tropical force and hurricane force winds! Works well for outside and a large shop, but we wanted to use it indoors when doing repairs around the house as well. Hooked this controller up, and it definitely slows the fan speed down. The fan doesn't even start to work until the dial on the controller is at about 60% (less than that the fan does nothing), and goes up from there. When using the controller the fan speed never gets to full speed, even at 100%. Not a problem because if we want the fan to run at full speed, we just unplug the controller, and use the fan as-is. We wish the speed control was better at controlling the fan between 0-100%, but at least it does make the fan usable indoors, whereas it wasn't before. With the build quality, I'm not really sure how long it will last, but time will tell.

I have two Westinghouse table fans from the 1950s. They move a lot of air but they tend to be a bit noisy. When I want a lot of moving air or I want white noise for a sleep, those fans are great. For TV I want much less airflow and much less noise. This controller works perfectly to slow the fan, reduce the air and cut the noise dramatically. I can use the ON/OFF switch without changing the speed setting and the fan returns to the preset speed from the night before. That's just what I wanted.The watt meter on the controller does not show what wattage of this fan. I don't know why and I really don't care. The controller does what I want it to do.

The media could not be loaded. El mio no funciona bien pienso deveria empesar en 0 y no es asi empiesa con el voltage algo y cuando le conecto lo que quiero para reducir el voltage sigue igual no cambia la velocidad nose si algunos de ustedes sabe si tendria que hacerle algo para que funcione como se debe o este no sirve

does the job

Works great. Not the highest quality but works good in the garage for use.
