Compact, cheap and of good quality
I use it for air filter fan speed regulation, and it works great. I guess it should not be used at the nominal value 4000W, but of significantly smaller power, to use it for a long time without overheating. Anyway, I am very satisfied.Read full review

Watch your wiring carefully!
The first one of these I purchased was wired backwards from what you would expect, and burned out!
Also, the connections are a little difficult to access, as the "permanent" plastic cover that protects the connections, all but prevents you from making access. (A curved screwdriver would help!)Read full review

An amateur's endorsement
This is my first effort to create/modify a speed controller for a DC treadmill motor for use in my shop. This seems to be working as expected and was easily modified to meet my needs.

Not 4000W
This controller has a single 10A fuse in it. I learned this after I blew it the first time I tried to control a 2500W load. At 220V, 10A gives 2200W. How did they come up with 4000W?

I liked it and it did what I wanted.
Unit was easy to install, wire, and adjust. I did wish that the mounting holes are slightly larger.

OK happy
thanks delivered OK. This item is OK but it could be better if there will be a numbered gauge behind the knob to know which volume it is set.
Happy
