These little modules do a great job of providing dimming to 12V LED modules. I am using a number of them in my old motor home. But, be aware, they modulate the negative side of the line. The battery positive comes in to the board and goes through a poly-fuse (great) and out to the motor (led) positive pin. The negative side goes through the PWM circuit. IF YOU ARE RUNNING A NEGATIVE GROUND CIRCUIT KEEP THE OUTPUT NEGATIVE ISOLATED. You can not run the positive line from this module to a light that is connected to ground. It must have a separate negative run back to the module.

Very nice laid out circuit, grippy handle. I don't like the terminals too much. They are the ones with an extra sheet of metal between the cable and the screw and it tends to let the cable slip. But these seem to be standard for many applications now. But other than this minor point there is really nothing that didn't convince. Also 5 out of 5 controller did function.

tested with oszilloscope, its real PWM and quite good for small applications.

great little dimmers for regluating your LED lighting or like i did model trains. they have a wide range of adjustablity and are working great !
