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

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.

Ordered these to control 2 small brushless axial fans. Works great. Wide range of adjustment and screw terminals hold tight.

The product did what it was supposed to do. The hookups are marked well and I like the compactness.

I broke down a portable water flosser and used this to create a wall mounted water flosser that didnt rely on batteries or a water tank. This unit provided the adjustable motor speed which translated to variable pressure at the head so I didn't saw my teeth in two. This controller really tied my project together, but i noticed that periodically the voltage spontaneously drops without adjusting the knob. This resulted in drops in pressure then a sudden hard jet straight to the Uvula.

Worked for a day, then the knob stopped powering it on and off and slower faster. It was stuck in ON, FASTEST mode. Will try a different kind of speed controller. This also gets REALLY hot VERY quickly. I burned my finger. My connected adapter was 12V going to a wiper motor.

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.

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.

Used this as a dc motor controller for a school project. The first set of boards came with the capacitors broken off. Basically Amazon packaged these with a wooden step stool that we also ordered. The boards and the wooden stool had a disagreement in transit and the step stool won. The issue was purely due to Amazon negligence and not the fault of the actual product. I ordered replacement boards and the non broken products worked great!

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

as advertised

Fait la job je recommande

Après plusieurs années, ca va super bien

Step voltage, not continuous variable voltage
