    Will bu used in the future with old PC-power-supplies for variable voltages. I have tested it with a power supply and measured the output voltage. The input was 7.2 Volts. I have used output at voltages of more than 25 V down to 1.5 Volts. The trimmer for the output voltage is extremely sensitive (10 turn potentiometer) so that the exact voltage can be set easily. The input voltage should be 5 Volt or higher for stable output.

    Step up step down DC to DC changer. It works fine for a small loads such as ventilators or small DC motors or other electronics. Like it for my DIY projects.

    Use it in a standard onwall splitting box. Due to ic step-down heat emission is minimal. As you can see, white is 24V in and via the screw on the resistor you can step down to 12V out (black cable)

    Small and compact. very clear where to solder the input and output cables

    Fast shipping and delivery. All modules are in the pack. I tested it and the product operates as described. Very useful, small enough and the price is really great. A good option for stabilizing my solar panel voltage or boost low voltage output of existing power supply modules to make them work in other applications. Very satisfied!

    I ordered three of these modules. I had never used them before, so I hooked them up to a basic adjustable power supply and measured the output while I made adjustments to the trimpot. I was having problems with the output voltage on the first one I tested, where it wouldn't go below 9.5V, even with a 5V input (I needed 3.3V). The step-up still seemed to work fine. I tried to figure out which component failed, but I never did. I even removed the trimpot for testing and resoldered a couple of surface mount resistors. I tested the second one, and it worked fine. I tested the third one, and it worked fine, but while I was adjusting the trimpot, I encountered the same problem and it jumped up to 9.5 V. I think this was probably due to an error on my part. I think that my alligator clip probably slipped and shorted something out. This also led me to believe that I probably killed the first one in the same manner. My advice is to be very careful when using this module, and to solder wires in place before testing. In my case, I feel that the error was on my part, and I will be ordering some more in the future, since they are inexpensive. Also, the circuit boards on all of mine were misprinted as part DSN600AUD instead of DSN6000AUD. Other than that, they are identical to the one in the picture.
