I bought this as speed controller for my lathe motor ( https://goo.gl/hJUo5g ). Build quality could be a bit better, but is is ok. Just connect it either to 24v power brick ( https://goo.gl/0CxNwS ) or if you want it in case with it's own power this nice power supply: https://goo.gl/ifsuWR

This order was just to build a few prototype machines. This controller, matched to a small 12 volt gearhead motor, performed just as we had hoped, with minimal motor noise, smooth range of speed control, and no detectable temperature rise on the heat sinks. If our prototype works out as we hope, we'll return for a larger quantity of these controllers.
