I noticed a couple of things while I was poking around in the GEL firmware update file:

Mention of a DAC8560 voltage reference:

Mention of two other models, 3051 and 3051A - a future/canned 500W version?

If you ask me, I'd be more concerned about the noise injected from the unit rather than the price itself: it's very annoying to have your measurement screwed up by things like that... Especially if you are going to make some ripple measurements or specification checks on other power supplies! Anyway, for less than 800 Eur it would be a fantastic choice for most of us!

Agreed. This is my main concern. My iTech is noisy as anything and also can't go down below about 10mA reliably. If this thing would be quiet and precise, I would look at replacing. Yes, an SMU would be better, but is 10x the price.

500W upgradeable by software license maybe?

it seems the DL3000 comes in two different color schemes:

And a photo from Batterfly :

https://twitter.com/BatterFlySrl/status/841943973321179136

Off-topic comment after I saw the Twitter photo you posted: what's with Rigol and their PSU GUIs emulating low-contrast LED displays? As if faking a 7-segment display using high-resolution graphic LCD wasn't silly enough, they even mimic the still visible "off" segments for added non-legibility :palm:

EDIT:
Or was the LCD "persistence" of the power readout just the effect of the unfortunate timing and/or long exposure?
I absolutely hate when designers mimic 7-segment displays. It makes no freaking sense. As a UI designer, you want it to be as usable as possible, so you should be choosing fonts that maximize legibility.

I sure as heck hope the "off" segments there are an artifact of photography, and aren't actually present. My guess is that it's an artifact, since the two upper display areas don't seem to have it at all.

Great idea !!!
Simone,
i m ready to pull the trigger for the DL3021  :P,  my application needs 24V at 25A ... 35A, can you make a quick test in this range please ?
P.S. (at Simone), any discount code as you have say in to the SDM3065X topic ?    ;)

Maybe you can try RIGOL-123-PASTA, or RIGOL-MAMA-MIA? :)

It's not clear from my reply, or the original comment I was replying to??

Look at the picture in:
And a photo from Batterfly :

https://twitter.com/BatterFlySrl/status/841943973321179136

See how on the watts display, the unlit segments are still kinda lit? (And on the V to a lesser degree.) Are the unlit segments actually there but less bright, or are they actually completely black, and what the picture shows is just artifacts from photography?

So you are not wondering about the DL3021 load at all, but about the DL700 power supply which sits on top of it in the photo, right?

I would expect the half lit segments on the power supply to be an artifact from changing numbers during exposure.

I wasn't wondering at all. Just agreeing with/elaborating on someone else's comment.

Sure. But you were asking for details on the DL700 (the instrument sitting on top in the Batterfly photograph, with the simulated 7-segment display).  In contrast, simone.pignatti had offered to take pictures of his DL3021, and probably does not have a DL700. Just trying to clarify...

Sorry if I messed up...
Yes we have  DP711 and DP712 to try together with the DL3021
Now I'm traveling, I can do from next Monday on

tooki, sorry again

ciao

Thanks to Simone(?) for answering my question on Youtube about the watt-hour display (which I totally think they should include in the battery test display). I also edited my second question and wasn't sure if you noticed that. I went through the manual, but can't confirm whether it's possible to log csv data on a USB flash drive.

I'm not sure you can download straight from the unit to a USB stick
However the Rigol Ultra Load PC Software is free of charge, you can get it here:

I am really hoping they release a new power supply with this new case and screen design.

Would be a big improvement over the old one.

And hopefully all 3 voltage outputs will be completely isolated like on the Siglent power supply.

I am wondering if two or more pieces can work parallel ... (via Digital I/O synchronization for example) as other manufacturer devices ...
