Those constant current mode overshoots are a major fail!

It's been a long while since I posted something, but I wouldn't mind winning one of those.

Just joined so I cant win, but love the quality. Hopefully they will fix the weird behaviour with a firmware update.

Looks like a good supply but then again I do like Rohde & Schwarz gear

The 200V serial range on this power supply looks really interesting and useful for some experiments.

Count me in!

Thanks

Hopefully this OC/OV overshoot is caused by an algorithm in the P/S controller and can be fixed in the next firmware release. Not that they know there is a glitch

I'm in, Nice PSU I would love to own one , Thanks for the teardown video.

etnel · « **Reply #10 on:** June 25, 2021, 12:17:48 am »

Would love one as a replacement for my 50$ aliexpress power supply.

You can never have enough power (supplies) so yes count me in. Thanks for the tear down.

If I got one, I would make a shootout with my HP 6632A from the late 80s.
Would be interesting to see how they compare and how SPSUs have evolved.

I'd love a beautiful R&S power supply to develop eurorack modules. Winner, Winner, Chicken Dinner?

I would be happy to win a free slightly used bench power supply!

andymouse · « **Reply #15 on:** June 25, 2021, 12:36:40 am »

Cor Blimey guv, would love to win one, a decent PSU !

amindavid11 · « **Reply #16 on:** June 25, 2021, 12:39:41 am »

The overshoot problem should not be in a $1000+ equipment, but I will gladly take it for free

chickenHeadKnob · « **Reply #17 on:** June 25, 2021, 12:39:57 am »

I'm in.

russan · « **Reply #18 on:** June 25, 2021, 12:40:52 am »

Ah man, I just bought a Siglent power supply for my home lab. A second, better power supply couldn't hurt, right?

nardev · « **Reply #19 on:** June 25, 2021, 12:48:37 am »

Is this enough?

iamdarkyoshi · « **Reply #20 on:** June 25, 2021, 12:50:02 am »

I'd love to score one of these, here's the homemade one made ages ago and killed somewhat recently:

(ah, BBCode tags bring back memories!)
It doesn't output anything anymore, the diodes are fine, I'm thinking the switching IC died.

Excuse the crudity of the construction, I didn't have time to build it to scale or to paint it!

Some wires and things (like screws) are missing since I've stolen some parts out of it. There's a fan under the mainboard to push cool air into the unit and the case had vents on the sides of the top and bottom

Fingers crossed I'll get selected, thanks Dave!

Rabid Badger · « **Reply #21 on:** June 25, 2021, 12:53:27 am »

I could use one of those on my new workbench.

Peeps · « **Reply #22 on:** June 25, 2021, 12:57:15 am »

That would be amazing to have, I'm seriously lacking decent test equipment.

graybeard · « **Reply #23 on:** June 25, 2021, 12:59:20 am »

I would love to have a power supply I can control over eithernet!

KaneTW · « **Reply #24 on:** June 25, 2021, 01:05:07 am »

Wouldn't mind one, although that CC overshoot is nasty.
