HiLetgo 12V~40V 10A PWM DC Motor Speed Control Switch Controller Voltage Regulator Dimmer for Arduino

Put this on the stove hood in our RV. The challenge was installing it in a way that the hood didn't 'short' the dimmer function. Works great, very happy now that we can cook, use our fan at an acceptable speed and not have to listen to it at 90 decibels.

It works as expected. I guess this is either a 5 or 1 star item - LOL! This one is a 5 star.

So much better and far cheaper than starter controllers in train sets.

It's only wrapped in a plastic bag. The heat sink was deformed during shipping. It fits the space on the exhaustion fan in the bathroom of my travel trailer. Now I can tune the speed smoothly so it doesn't spin like crazy with loud noise. Longevity has to be seen

We try to buy from the Ma and Pa places on here. Being disabled . We need to be price conscious. At "The Mother In Laws Place" It is an off-grid cabin, we run DC on a lot of things . We see no need to use the inverter 24/7. just so you can turn on a light when you come home . We use LED bulbs in ceiling mount fixtures that are marked 12-volt DC only. These are controlled by controller with a FOB remote. The controller is board mounted on our PV control center . We use a few of the controllers for different rooms to control each ceiling light . We also run the kitchen stove exhaust fan with DC . The fresh air intake system for combustion is DC . These are fused in our DC only fuse center . This fuse center is controlled by a service disconnect at the DC master box . We also run two AC fuse boxes on our PV board . One protects various AC 110 volt circuits in the cabin , garage and sauna . The other protects 220 volt circuits from the aux gen set and to the split ac/heat pump and the aux battery charger for when the PV and hopefully soon to be wind generated power are not enough to keep up. We run 8 - 6volt Rolls batteries tied by Buss bars . They are temperature and voltage monitored on the PV board and by the inverter unit. The power is inverted by a Renogy 3000 . It also has a multi stage charger built it with flow through capability . These are almost all protected by Breakers purchased here . We have a remote shallow well system that we use a soft start unit on . It lessens the instant draw on the system . It is all about power management. This is a semi detailed , general description of some of the off grid power systems we use . I am going to add this review to each one of the parts bought on here .

Excellent product. I use to control windshield wiper motor speed on Halloween projects.

The potentiometer is smooth, and the board mounted easily. Tested with a 12v DC battery system to control 120mm fans, rough vibration, and excessive heat: despite my abusive treatment, it has held up well. Any speed controller will get a bit warm during use, but this one has adequate heatsinks for it. The soldered side of the board has your inputs and outputs labelled; mine was a bit faded but still readable. Dial is easy to grip for large hands.

Work like it should.

Me gustaria que hubiera mas detalles y especificaciones tecnicas p.ejem frequencia PWM.

Plugged it into my circuit and and it worked just fine. No issues.

Great little speed controller works very well controlling a 12volt fan in my car. Good speed range and stepless control

J'ai acheté ce variateur pour me permettre de diminuer la vitesse de rotation de mon Proxxon Micromot 60 (12V). Le variateur du micromot a un fonctionnement de base de 5000 à 20000 trs/Min. En connectant l'outil sur ce régulateur, on peut tourner à moins de 5000, c'est idéal dans mon cas (maquettes plastiques) pour éviter toute surchauffe du plastique. Moyennant une bidouille pour brancher la prise du Proxxon, tout fonctionne. J'ai ajouté le transfo suivant pour mon usage : https://www.amazon.fr/Adaptateur-Alimentation-12V-5A-Transformateurs/dp/B07YWSDK87

ho preso questo dimmer per regolare la luminosità dei led devo dire che fa il suo lavoro egregiamente. è arrivato molto velocemente e ben impacchettato, devo dire che sembra di ottima fattura e robusto.
