DC Motor Speed Control Driver Board 3V-35V 5A PWM Controller Stepless DC 3V 6V 12V 24V 35V Variable Voltage Regulator Dimmer Governor Switching Build with LED Indicator and Switch Function

Used one of these as the controller for a 12v variable dosing pump for an Aqaurium (5-40ml/min). Really pleased with the finished item which works perfectly and saved myself a fortune on a shop bought one.

I have been using this for a while now and it still works fine.

Great product and great value for what it does. Just be a bit careful before you buy as you can run the input voltage as 5v-35v (high mode) OR 3v-15v (low mode) , the product description touches on it but not clearly, but you will have to pick one of those voltage ranges for the input. The default is the higher voltage range but if you want to use it in low voltage mode there is a solder bridge labelled on the back of the board (check product pics), which you would have to join with a blob of solder or small wire. The terminals are a little flimsy so they may break eventually if you are changing connections alot but not a huge issue due to the low price. 4 star due to great product, but the low voltage input situation could be better explained as the title implies 3v - 35v, but really you have to choose low or high.

This was what I was looking for

Works for the job intended, but a few point I think the threading on the knob should be longer I have had to use glue to hold it together on my project which wasn't thick metal. Also the supplied washer arived rusty which worries me how this has been packaged and stored (it does arived sealed)

I tested it. It works, but end up using different method.

Tried this to control a small 12v motor of the type that comes in faster RC cars and was too fast for the application I needed. I had an inline amp meter and found that this controller overheated and shut down around 1.6amps after running for around 20 seconds

Very good control regulator... Happy with purchase..feels solid and can trustable...

I needed a speed control for a heater fan. Works perfect.

Fine

Alles super, regelt wunderbar

foi comprado este regulador para controlar a reotação da ventoinha do exaustor de uma autocaravana. Funciona correctamente e permite controlar a rotação para que a ventoinha nao esteja a trabalhar na rotação máxima o que fazia muito ruido. Bom produto e boa qualidade

Très bon produit simple d'utilisation, branchement facile et indiqué
