DC 10-60V Waterproof Shell DC Motor Speed Control PWM HHO Driver RC Controller Speed Regulator Stepless Variable Rotary Switches 12V 24V 36V 48V Pulse Width Modulator

I inserted this into the wiring for my fish/deer feeder to slow the blower motor down. The feeder works well by itself but it throws the corn and fish pellets over too large an area. By slowing the motor down, I can control how far the feed goes by simply turning the dial up or down. It's been in use for a couple of weeks and is working perfectly - so far...

I tried different kind of controllers to make the fan work, this was one the best ones. Works great. Smooth speed controller. Easy installation.

Did not work out of the box.

The media could not be loaded.  I ordered one of these and what I am guessing is the potentiometer was faulty and did not swing through speeds properly. I returned and the replacement works exactly as I expect so far. Will see how it handles the season and update if anything changes.

Quality seems good. Used for a SXS cab fan I built. We will see if it last. Easy instalation.

Proper heat sinks proper caps proper potentiometer. Definitely not sealed in any way shape or form but otherwise excellent. This only works with DC motors that are rather simple. I've also detected no frequency noise from it. Most motor controllers tend to produce a whine around the 15 kHz or whatever frequency the system runs at. I've used frequency testers and even at 21 kilohertz where this runs at it produces no noise in the coils on the fan. Absolutely impressed with it. 10 amps continuous is a little optimistic it's more like eight or nine but it definitely does that. 20 amps burst it definitely can do. Absolutely love this thing I've bought more expensive motor controllers that are worse. Keep in mind I got this in 2020 and this is the 2020 variant I don't know if they've cheaped out.

I purchased this to control fans in the overhead of my Kawasaki Mule UTV. It seem to work very well so far. Easy to wire and the terminal blocks handle 12/14 AWG wire. For the price it works well and hopefully it is waterproof as the description has.,

Bought 6 over the years. Did well except last one, which does not work, it's only an on or off switch. Speed is full speed no matter where you turn the dial.
