2pcs DC 12v PWM motor speed controller,1.8V 3V 5V 6V 12V 2A Speed Adjustable Switch Module, Variable Voltage Regulator Dimmer Governor Switching Build with LED Indicator and Switch Function

Awesome little module that handles SS well, great for controlling small fans/motors. There could be two minor improverments: 1) The led indicator is SMD, in a weird location next to the pot (looking down on the board). Great as an indicator when testing but useless if mounting in a case. If there was headers for an LED is would be better. 2) The terminals are pre-soldered to the board - again ideal for quick/ease, however when using the board in a case/perm fixture I would de-solder this in fav of soldering the connections directly to the board. You find lots of modules come with the header terminals but you have the option of soldering. Apart from that it works really well, extremely well for the price!

5V usb supply into this module then a 12v fan yields great results. Controller and knob moves smoothly and mounts easily with included nut. With this simple setup, the fan is able to operate through a full range of RPM'. LED power indicator built into the PCB is nice and bright. It is easily visible when I poked a pin hole next to it and works nicely with a blob of semi-transparent sealer / glue to act as a diffuser. Good value items for your home project. Have since acquired more.

Works very well. Beware, the connection markings are underneath the board, so bear in mind when locating

Used to control d.c. motor speed for a telescope drive. Worked well but note the output voltage is +V supply on both leads at 0% duty cycle and is pulsed to ground to achieve PWM. Depending on your circuit this may be a limitation.

I wanted an adjustable motor to run a model windmill. I’ve tried others unsuccessfully before trying these. The adjustability is really accurate ranging from extremely slow rotation to very fast so there’s plenty of range to finely tune the motor to the perfect speed.

Unfortunately one just didn't work, had to get a refund and then order again. Great that it comes with the wire and they now work perfectly.

Ok

Fonctionne très bien Mais le moteur DC 3V-6V s'arrête au bout d'une ou deux minutes, même à vide, sous 4.5V ! Pourquoi?

Ser bra ut men ej testade!

Die Artikelbeschreibung erwähnt es ja nicht ausdrücklich, aber auch für das Dimmen von LED-Ketten und LED-Filament ist dieser kleine Helfer die erste Wahl. Ich habe die Schaltung mit 12-Volt-LED-Ketten (COB) und 3-Volt-LED-Filament im Einsatz und kann nur sagen: Plug’n’Play vom Feinsten! Dass das hochwertige Poti dann auch noch mit einem On/Off-Schalter ausgestattet ist und alle Teile zur Befestigung mitgeliefert werden, macht das Set aus meiner Sicht perfekt. Also ich kann nur sagen: Ein Top-Produkt zum unschlagbaren Preis, volle Punktzahl.

Me llego rápido funciona a la perfección

Funziona perfettamente ed è facile da installare. In prossimità dei connettori è indicato anche dove colegare i cavi di alimentazione e dove collegare i cavi del motorino. Viene spedita una confezione che contiene 2 regolatori di velocità singolarmente impacchettati. Per ciascun regolatore di velocità sono inclusi nel prezzo anche una rondella e un dado per il fissaggio e una manopola di plastica esterna per la regolazione. Oltre a regolare la tensione, il pezzo funge anche da interruttore. Sul circuito è presente anche un micro led rosso che si ilumina quando vi è alimentazione. Davvero un ottimo prodotto.
