RioRand 7-70V PWM DC Motor Speed Controller Switch 30A

Brush motor speed controller.This pwm controller was used to control the speed of a DC motor in my air conditioner. I am using solar panels to generate the power. The efficiency and wide operating range of this device was a perfect fit for this application.

Tried using as a voltage regulator for the kids peg pegero john deer electric tractor. It lasted about 10 minutes and melted the tractor wiring. I set the output voltage under load to 14 to 16 volts. I've ran 18v in the past. Suggest sticking with a regular 12v regulator for longevity. The knob is extremely too sensitive for this application. The speed controller however was not at fault.

Great product to use with a 12v oil/diesel transfer pump

Works well for DIY halloween displays

I needed to control the speed of a track actuator to match the speed of an older unit. The precision needed over 30 seconds was extremely precise. This unit has the resolution in its potentiometer to handle it. My only gripe was that the labeling of the terminals is on the bottom. So I had to unmount it and make a note.

The speed controller is not working. This is the third one I've purchased and the only one I've had any issues with. I used the previous two to test the issue and they worked fine. Based on another recent review on 3/5/25, I hope this issue can be resolved soon because it almost cost us Ride on Car and caused melted wires.

Have several of these in use now, they keep working and I keep finding more uses.

Works well with all the kids cars I put it to but I don't know what happen to the smaller voltage one . I think it might have blew the circuit but when I used it for the 12 o man the car is so fast and my kids love it. Very good option for making your kids car fast or making old ones fun again
