Hello, Kevin

There is pdf manual on product details page, https://m.media-amazon.com/images/I/91y5DdCGyJL.pdf

Hello Dave Pellegrino,

Notice: after adjustment, please upplug the metal from output ports, just put back 

No converter can control how much current the load should draw, actual output current mainly  depend on load.   Converter  only regulate current when load current is over preset limit. For example, preset value is 10A,  load draw 20A,it will limit load current to 10A.

Hello Mike,

Do you mean the TTL level is 5v now? But it request 3.3v .

Hello Dave Pellegrino,

Did you receive this manual? https://www.droking.com/cs/wp-content/uploads/2022/09/200624_200625.pdf

The switch is pushed left, you can adjust  current limit value. If it is pushed right, that is to open output.

About no-load current adjustment, without load, current is zero, which can’t be adjusted,  so you need to pull out the metal insert under current adjustment then connect output port. After adjustment, please put back the metal insert.

If you don’t need to limit current, you can  neglect that,  just push switch right and turn current potentiometer clockwise  to maximum.

Best regards,

Hello mounty,

Parallel connection is not available. And address 1-26 just save output setting parameters.

Best regards.

Hello Mike N.

Are you talking about the 2001710003? Please notice  one litium battery voltage is  4.2v in this program, then L2 means  4.2v*2=8.4v instead of 48v.

Best regards.

Hello George，

Is it possible for you to draw a simple diagram to show your connection. And please notice it is for DC measurement. The hot wire you mean should be positive or negative, is it right?

Best regards.

Hello,

Currently we don’t have buck converter can output 20A. The maximum output is 12A at 60V.
