DC12V-60V/20A Motor Speed Controller, DC Motor Speed Controller, Forward/Reverse Electric Motor Speed Regulator, Suitable for DC brush motor.

Built a motorized Bead-roller and this was just the part that I needed. I could have put one together with misc other parts, but this all in one solution was PERFECT.Solid unit and so far is working as expected.

The media could not be loaded. I saw someone else use this dc motor control switch to be a controller for G scale trains and decided this can be an affordable way to control a train. The switch is designed to be installed in a panel but I will make something for it. The connection to the speed control switch is easy . On the back are 4 terminals. 2 wires(power and ground from the power supply) and two wires to the track (power and ground) the switch can easily handle the power of a garden scale train Which generally run between 14 and 22v with amperage between 2 and 15amps for g scale trains. Watch the video to see it control a train.

Works as expected. Easy to install

We used this product once. Now it is not working. We have 12 volts coming into the switch but no voltage coming out. Fuse is still good. I can bypass switch and everything works great.

To be fair I haven't installed this yet but you can't really connect wire that is large enough to carry 12v @20amp to the connectors. I suspect before I can run the motor using anywhere close to 20amps this thing is going to melt. I should know in a month or so.

Worked perfectly for a pond feeder that had no adjustable motor speed control. Lifetime product I’m sure. Excellent price

The media could not be loaded. I ordered this speed controller over 2 years ago to use with my tire truer that trues Mini-Z tires for 1/28 scale R/C cars, but it’s been sitting around because I didn’t know what size spade plugs to order for it (it takes a #6 stud by the way that I finally found at a local wire store).It is powered by my 12V 24A MuchMore Racing power supply, but I needed something to control the voltage to the tire truer, which works best at 5-6V and that could quickly and easily reverse the polarity of the current depending on whether I was trueing right side or left side tires. This speed controller does both and works just as it should, but I’ve only used it to true one pair of tires so far, so only time will tell how long it will last. It is pretty light weight and doesn’t feel overly solid, and the knob doesn’t turn smoothly throughout the entire range of rotation (which is why I gave it 4 stars), but it does what I need it to. I will update this review with more info on reliability once I’ve used it more over the next six to twelve months.

After a year of constant use this has proven itself in regulating water flow through the solar collectors
