DC 12-60V Motor Speed Controller 20A Adjustable PWM Controller Switch Forward/Reverse Electric Motor Speed Regulator Suitable for DC Brush Motor

Works Great. Tested it with a 12V to 24V DC Motor at 19V 0.4A. The Speed knob is smooth and clicks off with a good feel. The Off/Direction switch works great. Crisp switching feel between Clockwise/Off/Counter-Clockwise. Very good quality and I am happy with this purchase.

This item works really well as a speed regulator for a recirculating sluice. Wire it into the battery and out to the pump and you’re in business.

This PWM DC controller is rated to 20 amps, which is the reason we purchased it for a project that required a conversion from 24 vdc to 15 vdc at 12 amps. In general, running a similar device at roughly 50% rated capacity should be easily accomplished and at stead state conditions. On the bench the device operated perfectly at low load levels (under 1 amp output). Once in the field and connected to our intended load at 15 volts and 12 amps, it got hot and smoked within 2 minutes. It now apparently has an internal short and is no longer operational. We would recommend a maximum load of only 5 amps rather than the stated 20 amps.

I used this to control the speed on a Christmas game I made with a conveyor belt. I tried to use a variable output power supply but this gave me a lot more control.

This controller is mounted in my greenhouse to control the speed of a recirculating ceiling fan. It works perfectly except that the controller knob indicates lower numbers for higher speeds and higher numbers for lower speeds, meaning its indicators are entirely backwards for functionality. It is a bit awkward as a result but the unit is neat, clean, and well-made. Someone simply got their wires crossed, literally! LOL!

This is the best control that I have tried, if you are looking for a control that works this is for you

It was working very good, then stopped and never worked again.
