RioRand 7-80V PWM DC Motor Speed Controller Switch 30A

work extremely well for kids ride on vehicles. regulate tol speed for some of the younger kids we have

This was a game changer for my son’s power wheels quad. I spliced the plugs in and use it on two different types of machines. One is the Perego John Deere tractor and the other the Yamaha electric raptor. I use Ridgid batteries 4amp and 8amp they both work great . You can turn the dial up and down with voltage resister for speed control. You will need 30 amp fuses if your kid rides hard. They pop once in a while when the machine is pushed hard.

I do my lawn care and my sons and I do a few friends' lawns. I needed something to regulate the GPM my sprayer distributed. The pressure regulator does not slow down the flow enough to spray prodiamine effectively so I got this device and hooked it up. This device slowed down my 5.5 gpm pump to one gpm. I needed a little more than that of course but for prodiamine, you want to get large droplets into the soil for best results at the recommended rate. Exactly what I needed. Now I can spray my fertilizer, weed treatment, and pre-emergent, all with the same setup. Just set the correct pressure to get the flow I need, choose my spray tip, make sure my 12v battery is charged, and off I go. I have over 20k of lawn to spray so the little back sprayer is too much of a hassle. I use a 26 gal sprayer setup with a 50ft hose. I add 21 gal of solution in the tank and it's done in 35-40 min. Awesome product.

I used this to replace the blower speed control in my 05 Ford F150, the big resistor blew for the third time. This is working perfectly and with some creative customization I was able to use OEM control knob. I also repurposed the plug to tie into the factory harness. I deducted one star because the external fuse holder uses 18 gauge wire, basically a heating element with half the rated current at 12V! I would use caution with the included external online fuse and replace.that with something more robust if you plan on more than 10A at 12V The unit has a built-in 30A fuse, and in my case it was already on a 30A dedicated circuit for the 260W blower. The only other little thing is there is no provision for mounting. I would buy again for another application, should one arise.

purchased this ca Feb 2025 but just got around to using this and as others have described, worked GREAT for about 5 mins and then ONLY FULL POWER (no power control). I have a similar looking PWM from another vendor (DC Motor Speed Controller PWM Controller, Enmja 7-70V 30A Adjustable PWM Motor Speed Regulator 12V 24V 36V 48V) and this has been used extensively for about 1 year and it's fine. again, these 2 units LOOK ALIKE but clearly they aren't the same. also, I did some voltage measurements on the 2 units initially and the defective unit (before being used) required advancing the rheostat near 2/3 of its entire travel before it registered anything. that was until the controller failed resulting in 100% output and NO speed control at all. I'm going to order another of the previous model (still offered by Amazon as of 6/2025) since my experience with that has been positive. but I'll avoid this one that is defective. I'll also tear it apart to see if there is anything fixable (and cheaply) and if I come up with a solution, I'll post an update. one note: as others stated, when it works, it's great. it just doesn't work for very long.
