Gebildet 3pcs Mini DC Motor PWM Speed Controller, DC 5V-35V 5A Speed Adjustable Switch Module, 6V 12V 24V Variable Voltage Regulator Dimmer Governor Switching Build with LED Indicator

Used to replace failed speed control on a Halfords 240v type dremel. Works perfectly with added bonus you can alter the lowest speed using the pot on the board.

Everything is great. No comments.

I wanted to replace a simple fan speed controller on a barbecue that was not very variable. This one works a lot better

Very good modules and they work well.

Great purchase Have used these for speed control in my railway modelling. Now using similar to control voltage to backup supplies to solar / battery backed lighting in my garden.

I've always had the problem of typing at night when only a side lampshade is in the living room. A backlit keyboard was only part solution, as I couldn't find a decent one, so I went back to old-trusted Logitech and added a LED strip under the monitor. This had two problems: the light was on a wrong angle so not reaching the keyboard, and too bright so caused glare. Solved the former problem with a 3D printed housing for the LED strip, to keep it on a correct angle. While this little board solved the glare problem, a USB connector was soldered to it, the output to the LED strip, so I can adjust the illumination to the keyboard to any intensity. Problem neatly solved with very little money!

Utter garbage, item was faulty from the start only outputted 240v and the trimmer pot had no effect on the output side voltage at all Don't waste your money buying from this seller

Purchased 3 pack. First one tried with 32v power supply (ex printer power supply. voltage checked before use at 31.6v) no load (i.e. no motor attached). It blew at about 2/3 of the dial roataion. Supposed to work up to 35v !? This PSU provides both 16v & 32v so tried second one with the 16v line and works OK. Second one tried with several power supplies 5v, 10v, 12v & 16v and working OK for now. Also working fine with load (motor from printer rated for 12-42v). Havent gone above 16v so far.

Keurige module, doet precies wat je verwacht. Voor wat het kost kun je het niet zelf maken.

Ich bin Anfänger aber meiner Meinung nach gutes Produkt!Habe es für einen Heizungslüfter gebraucht. Funktioniert einwandfrei.

Exactly what I needed, works perfectly with adjustable/dimmable light ballast 😉👍

3 burn out when I was testing, return the rest.

I bought these to control a small motor for an ice fishing automatic jigging machine. They work just great. Smooth operation. I would certainly recommend them.
