The 500mA sink limit

Hello,
When in a constant voltage mode there is a 500mA current sink capability but what happens if it needs to sink more? is it safe to go over it as long as the voltage won’t rise over 5V?

Hi and welcome to the forum!

Yes, it is safe as long as you do not exceed 5V on any pin.
However, you can not trust the measurements above 4.2 if you are connected only via USB. You need to have a DC adapter plugged in to trust the measurement all the way up to 5V.

With automation toolbox, you can fully control this current sink and sink up to 2.5A.

Best regards,
