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

Works Very Well, Highly Recommended.
I used this to control a salvaged car heater blower to run a portable Blacksmiths forge where no mains power is available. I did have an issue with the fuse blowing, but that was my fault as the blower was drawing too much current on full whack. Highly recommended.

Perfect for powering 12V PC fans
I’m using this to power 2 12V PC fans via a 12V mains adapter. By cutting the cable of the adapter and connecting the postive and negative to the power terminals on this unit, and then connecting the positive and negative of the fans to the motor outputs on the unit, you get fans with controllable speed! Very happy with the product. Will buy again.

Great little PWM module - pity it didn't last
Purchased this as a speed controller for a 12v motor in my home-built magnetic stirrer. Works fine, although the physical potentiometer mounting is not extremely robust and could be better. Easy to wire up with clear instructions. Update 28th Dec - unit failed and output is no longer adjustable, outputting 100% continually. Disappointing, load was a low current motor well within specification only drawing a few mA. High quality regulated 12v supply was used as well. Naturally, the unit failed outside the return window. Checked PCB for dry joints or overheating components etc and none found. Rating adjusted accordingly.

China does it again.
Does exactly as stated and controls the speed of the cage in my Model mine shaft. Delivery is long since it comes from Hong Kong! But worth waiting for. Great price and value.

Current voltage
Used to control a proportional hydraulic valve removed the 100k pot replaced with a22k multi turn pot with end stop resistors to give a minimum fluid flow and a max fluid flow this gives a very fine control over a hydraulic motor the device is very good value for money Would be nice if the pot was not mounted on the board allowing for remote operation Will buy again for other projects

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

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

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.
