RioRandUpgraded 6V-90V 15A DC Motor PWM Speed Controller 1PC

Got my cooled seats in my f250 perfectly I wonder how long there gunna last . I just wish they came with a sticker in the box.

works well! Thank you China

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.

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.

made well

Total garbage. It arrived brand new, unopened, zero damage. Looked to be in perfect condition.But it simply DID NOT WORK. NOTHING. Nada.Reading the reviews it seems to be a common issue with this and several other speed controllers.

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.
