Aweking DC10-60V 12V 24V 36V 48V 10A Motor Speed Controller,PWM,Adjustable Driver,Max240W,with Switch Potentiometer,10A Fues Overloading Protection,5%-100% Speed Controlling

Bought this little motor controller to use with my Upgr8 12 volt 12 inch Radiator Fan. I’m using this controller to adjust fan speed and current draw in my solar powered shed project. This appears to be a great combination for venting heated air from the inside of my shed. My voltage from my solar controller fluctuates from about 12.1 to 15.4 volts and this controller works with this voltage. I like the adjustable potentiometer with off position that allows me to control the speed of my exhaust fan. I also like being able to control the current draw of my fan at the same time. The main thing that I feel needs to be improved with this controller is the mounting layout. As of this writing there is only one small hole and one small slotted hole for attaching to my mounting surface. I would like to see 4 mounting holes. But, I have improvised my mount and the controller has been working well for the 3 days I’ve used it so far. (My fan current varies between about .2 - 6.5 amps, normally set to about .3 amps). I would recommend this controller for this type of application.Update 5 months later - After using this controller for 5 months I still like it but I have encountered anomalies. Seems like the unit tends to stop working at times in my shed when the temperature reaches somewhere around 100 degrees. It may not be designed for temps that high. Anyway a few days ago it stopped again and I took it out and opened it up. I resoldered some of the leads and traces that looked questionable to minimize any cold solder joints. Since putting the unit back together it has worked without any further problems.

This unit is non working. Like the other reviewer, I also waited too long to complete the project involving this microelectronic and now I have a fancy paperweight. SMH. After troubleshooting the board, I think I have found the issue, I will update review with good news hopefully. My current opinion.....for the same price range, you can go with a much much MUCH MORE REPUTABLE seller, DROK, AND ALSO GET A DIGI DISPLAY AND EXTERNAL POT AND ROTATIONAL DIRECTION SWITCH.

Using this to slow down an automobile window motor that opens/closes a door. The controller handles it fine, even when the motor stalls at the end (stall current is about 5A). Really nice heavy duty screw terminals, and handy exposed hole and slot on two corners for mounting. The only slight issue was that the top of the case was somewhat caved in and was in danger of touching some of the components inside, but I was able to use a small screwdriver in the ventilation holes and lift it back into position.

If I could give it no stars I would. Did not work and I procrastinated too long and could not send it back. Maybe I can save someone else from wasting their money. Buyer beware!!!!!

works great controlling fan speeds :)

works incredibly well
