I already looked at that and it is not actually correct, which is why I need to hear from others what the 4121 and 4323 maximums are, they do very slightly more than it says, and I want to allow the definitions to use it all.
KungFuJosh:
Scott's correct; even the SPD3303X datasheet specs are slightly conservative compared to what the device will do/show.

Which could be a wasted exercise if there are minor variations between units.
What size sample might you consider sufficient to make assumptions on the max output level across all of the 4 outputs and 3 models.
IMO you would be better to use the rated max datasheet output so to be sure all models can meet the programmed output.

Unless otherwise noted, all specifications are guaranteed within the temperature range of 25°C±5°C with warm-up time of 30 minutes.

Q
Have you confirmed output higher than rated can be provided using the command set P51 ?

What I listed is the settings that the unit allow you to go up to, so from my list, Ch1 could be set to do 15.15V and 1.515A, as set on screen, etc.
I'm not talking about a measured output voltage on the terminals, but the maximum setting that can be made on screen and via SCPI.

Can people please confirm the absolute maximum settings for voltage and current on each unit, the data sheet gives general setting only but they can go over that slightly, the quickest way is to select the first digit and spin the encoder clockwise, it will max itself out.
[...]
Please list in the same way, once I have this information I can publish then test controller definition.
