RioRand 6V-90V 15A DC Motor Speed Controller PWM

Using this to replace the controller on a Razor drift cart. It's a dumb controller but the price makes sense and it works well. It is has heat sinks you could screw into. It might not last for my purpose but that's why I got 2

I needed a pwm to replace a speed controller for a 24V dc motor. This worked perfectly. It was easy to install and works great. The adjustment is smooth and precise.

I ordered this for our Fantastic Fan in our trailer; I wanted something that can handle the amperage (although this unit may be overkill) and that would fit in the original housing. This unit seems a little large however it does fit. Installation isn't necessarily the easiest but I had plenty of wire and connectors to get the job done; if you decide to use this in your roof vent, just make sure you know what you are getting into. I completely removed the original 3-speed switch and replaced it with the knob, which works just fine in that original hole. The board is mounted to the circular fan opening right next to the switch. I used spade connectors to connect this unit without cutting any of the original wiring, and of course had to add some wiring as well. Once back together, there's awesome control of the speed now, and it appears to use less power at lower speeds than before. There's no whining out of the motor at all.

I rewired my over stove/oven extractor to run at 18v dc using a step up transformer and this rheostat now controls the speed using from 0 to 18v. Now I have a greater range of fan speed. Also upgraded the lighting to three 12v LEDs, now also running up to 18v with a dimmer. So far it all works. This controller with its remote rheostat fits my application.

Good product

Worked for one day. Then just stopped. No voltage output. Annoying.

I'm using this to drive a 24V 4 A motor. The heat sink gets barely warm after continuous running at reduced speed for hours. I'm planing to buy a few more of these for an industrial project. There a few things to be aware of however. The boards I received had quite a bit of solder flux residue on the bottom. This can be cleaned off easly with a little alcohol. The wiring on the potentiometer connector does not follow convention. The Red wire is ground , the Black wire is +5 V. Convention is the opposite. This controller is not going to use the pot but will be driven by a microcomputer. The external control works smoothly with 0 V being off and +5 V is full on. My take on the negative comments are as follows : The terminal connector not being wide enough can be solved by using a ring lug rather than a spade lug. This has worked out well on my test setup. The large 470 up capacitor exploding could be a failed cap. or over voltage. The application was a 90 V motor on a tread machine. The drive voltage was probably not regulated but just rectified line voltage which would exceed 100 V . So the 100 V cap. would be destroyed by over voltage. I recommend these units very highly. The cost is well below the cost of components and the PC board.

This PWM seems reasonably well made, has nice set screws for contact wires. Used this on a winshield wiper motor to help regulate wiper speed, but alas, the low position of the knob provides the same wattage as does the high position. So I do not think this purchase was wise. The module works good, just does not achieve the goals I was aiming for.

I bought this as a motor controller for a camera slider I was automating. This is dynamite!!! It's voltage input range is fantastic, And the wired pot leads make for a versatile mounting arrangement. It works great, and works all the time. I'm just driving 12V through it now, but plan to up it to 24v, and it's great that it can more than handle this. No worries by purchasing this unit. If you need one, this is the one to get. Ordered on Saturday, scheduled to arrive Tuesday, but came on Monday! All around, a solid purchase. So fear not my Amazon shoppers!!!

Parece de juguete.mala calidad

Works great, hope to buy more in the near future.

Mais oui c’est un bon produit 👍🏼 le seul différence qu’il y a pas boîtier en métal... c’est nous autre qui fait sytème et le montage qui nous plait SUPER Bon prix bon service de livraison très satisfait merci

Works well. I installed it to regulate my electric bike that had its regulator toasted. The 15A is right at the limit of power of the motor so the fuse blew a couple of times but if I am careful not to force it at max power, the new fuses last longer. Excellent for the price.
