Yes, in Ampere mode, the maximum admissible DUT current is 1A for the Ampere meter mode, and 600mA in Source meter mode. Please refer to the PPK2 user guide for details.

Is the 1A limitation also present when using the PPK2 in Ampere mode?

The PPK2 can indeed maximum measure 1A without risking damaging it, so it's not really a good fit to measure the current on products drawing more than this. It's designed to measure current on our low power SoCs/SiPs that rarely exceed 100mA I'm afraid.

I guess you could implement some kind of fuse to make sure current is cut if the current gets close to 1A, and then measure to make sure the PPK is fine, but that could affect the measurements accuracy depending on how often this fuse would be triggered.

Unfortunately we don't have any power profilers suited for measuring higher currents like this, and I think a power analyzer like the N6705C from Keysight, but they are definitely more pricy.
