Hi all...I hope I'm posting this in the correct place...I'm attempting an adjustable voltage and current bench top power supply. I'm using a XL4015E1 DC-DC buck converter module. It is rated 4-38v input, and 1.25-36v output. The module comes with small blue rectangular pots (with the little screw on the top). I want to replace those with a 2.2K ohm 10-turn pot. The ones I have are WXD3-13-2w.
Here's the problem...when testing the converter module as is, it works fine. But when I connect the WXD3 pot (and I'm not sure I'm connecting it correctly, as seems to have 5 posts, but I've tried every configuration possible (using a 12v power supply). The problem is with the 10-turn pot, the output only measures to 9.4volts. It will not go any higher. I put the original little pot back in with my 24v power supply, and it reads up to full power. But the 10-turn pot still only goes to 9.4v.
Obviously I'm pretty new to all this....just entering into the hobby of electronic tinkering....any and all help is appreciated!
Thanks!
