DC Motor Speed Controller, Brush Motor Driver Controls Module DC 9V-60V 12V 24V 36V 48V 60V Motor Pulse Width Modulator Regulator 20A 1200W PWM Monitor Dimmer Governor

Powers two small fans in a side by side, the knob works great for adjusting, alil touchy but great. Husband had this hooked up in no time and installed great.

I used this controller to install a fan in the ceiling of my RZR. The controller worked fine for one trip. The second trip, the solder joints all failed on the knob. Absolute junk wire is used on these things. Do not bother buying this unless you are comfortable soldering new wires in place of their garbage.

I have 2 of these controllers on my fuel pumps used to fuel RC jets. The variable pump allows reduced pressure for fill so as not to rupture internal fuel tanks and can be run at full speed to defuel when necessary. Power is supplies by a 3S LiPo battery.

I liked the fact that this this item is versatile. It can be used under multiple voltage systems up to a certain point without issue. However, I tried it on a go cart instead of a pedal throttle, but it didn't seem too get as much power out of the motor as it should have. I really don't know the reason behind that, but I know that with a twenty four volt battery and a 250 watt motor, my five year old should be cruising along, but the reality is, it wouldn't even move forward.These are ideal for a fan (under less load) when I lift the rear end off the ground, those wheels spin very fast.

Excellent value, performs well. The negative issue is the switch is hard wired on a short length of leads. It is designed to flush fit into a cut out on panel or plate metal. The switch wiring should have plug in connectors instead of hard wired. Hence, it becomes necessary to cut the wires, install switch into cut out on panel then either solder or wire nut the wires back together. That could be easily modified to simplify install of 3 way switch.

I purchased this speed controller to drive a PMDC Right Angle Gear Motor 12V Reversible 50 RPM (that I also found on Amazon). This device works as expected. The quality of looks good. The assembly would work really well as a panel mount; because it already has a nice aluminum enclosure. I currently have it housed in a plastic project box. The motor is driving a DIY welding (MIG) positioner. Works great for my application!

Worked great for about an hour of use. Then just quit.

The compact size of the unit makes it fairly easy to locate installation point. The attachment of the speed control is good, but the power/reverse switch being soldered to the unit requires removal by desoldering or cutting and splicing the wires, so switch can be mounted. Overall very satisfied with the operation.

I bought two & one arrived with no negative wire attached. Hate to think about what this means for quality control.
