RioRand Ver.2.0 Premium PWM DC Motor Speed Controller 1803BK | 1.8V-12V Max 15V 2A with Self-Recovery Fuse & On/Off Switch for DIY Electronics Low Voltage LED Dimming

Works great. Wired this into a 12v rock tumbler to get greater control over the rpm’s. Increases/decreases rpm’s smoothly. Easy to install.

I used this for a small fan I needed in our work truck. I liked it and it was easy to use. However, I was not able to switch the wires around and make the fan spin in the opposite direction but I have a extremely limited knowledge of electronics so it more than likely my fault. I would buy again.

I got this to regulate a tiny 6 volt motor I use to drive a marble run I built. It works just fine and doesn't take up much space.

would have been nice to have instructions as to where to place wires

I picked these up hoping I could get them to function in the bunk fans for our Pop Up trailer. They are actually a perfect fit and work great!.There is some wiring and drilling necessary to make these work. The job is easy if you know what you are getting into. I removed the resistor from the low speed switch and wired these in with the high speed switch. The knob on these have a click/off position which is perfect. I noted that although during the day you can't see it, at night you can see there is a red LED on the board which glows through the plastic housing of the bunk fan but it is not annoying at all. At low speeds these are perfect, and there is no motor whine.

The first controller lasted 11 months, the second only eight on pet fountain pump flow control.UPDATE: Requires nearly full power to start. A power interruption kills it until full power is applied again.

Seems to be some leeched power through the potentiometer/switch. Have it connected to a 12v motor, I turn the potentiometer all the way down to the off position, and once there, the motor starts to spin again. appears there is current flowing through the switch even though it has been turned off. The variable speed aspect of the controller works well otherwise.

These little fan controllers work well for managing fan speeds of typical computer fans. I originally bought some of these a while ago to manually adjust the fan speed on my PS4 and have since used them to make little table top fans from pc fans that I've salvaged. They are PWM controllers with a built in potentiometer to make any fan variable speed.

Fait la job je recommande

as advertised

Après plusieurs années, ca va super bien

Worked well to control power output from a single 18650 cell (3.7V) to battery powered lights to make them dimmable.

Step voltage, not continuous variable voltage
