Past, Present and Future: Siglent SPD3303X Bench Power Supply

Siglent have sent me their SPD3303X programmable power supply and as expected it is very nice. In this video I am showing a few of its features, suggesting new firmware features and testing its output ripple under load.

Absolutely go for it! I'd love a cheap 4-quadrant source, and I'd love it even more if I could buy it in kit form, or just a bare board and a BOM.

Watching a PSU power & ride a e-skate board tickled my fancy more than it should have.

95% of the time i have no clue what you are talking about, but i still love your videos. Must be that awesome accent.

[Corgitronics]

Go for it! But, if you build the source device, what will I do with my 2450 & 2460 units?

Hoping and praying that you revisit the OSMU one day 🙏🙏🙏

M8, if you get that project done, I will buy it full price right as it's available. Hot damn, that's an awesome project!

Great to see its working that well on a skateboard ;-)

Great idea! Make it tough too. I have a variety of hobbies that use DC power (3D printing, automotive, aluminum anodizing, hobby electronics) and having one power supply that can cover all these bases would save me so much money. 30 vdc @ 10 amps covers 95% of the projects I do.

I bought the Siglent SPD3303X-E which is very similar this one. Siglent seems to be the best bang for the buck currently as I have also bought other equipment from Siglent after exhaustive comparisons with other manufacturers.

Can't wait to have some details and schematics explained!

Great idea! Insanely great idea! 3 channels (+/- 30V, 10A each?!)
I instantly paused the video when I saw the quadrant. I watched the last 2 minutes 3 times!
I would love to see lots of videos for this project.

What if it also had an ADC for external input that we could use to correlate things?! We could measure motor torque, temperature, and lots of other things in relation to power.

The current sinking function is usefull when testing batery powered/backuped things.
But the reversable polarity is can be dangerous in most of test situation.
If we call it an low frequency power-signal generator it can be high more undersandable. It can be usefull to test inductors in production.

[anonymity]

That's a great idea! Consider another one sold when you have it finished

[rubenafonso]

Very good idea! Please make that equipment, it will be very useful for both hobbyists and professionals

[Thomas-obfe]

Go for it, i would be amazed to see your development process as it's going on.n

[danbir]

Great Idea - I am in!
Especially the combination of a power supply together with a simple wave form generator is what I am looking for, for a long time! As a hobbyist, space is always an issue...

[aronhighgrove]

Maybe I missed it, but I couldn't see any mention about improvements to the binding posts, compared to the teardown on Dave's EEVBlog. The "loosy-goosy" fit and the wrong horizontal distance of the + and - posts are definitely quite significant disadvantages.

OSMU, cool name. Looking forward to see your progress.

I'd love to see an approximate price to quickly see if it's in range for a hobbyist or strictly pro grade.

Idea of programmable ( ideally opensource ) high-quality 4Q PSU is great, but maybe it would be better to scope only on high-quality PSU and nothing more. Build 4Q function generator as extension for 4Q PSU ( requiring 4Q PSU for supply ) would have several advantages
1) not everybody wants to have 4Q function generator at all
2) some want to have more than one 4Q function generator connected with phase sync and some common potential ( 3p / stepper motor testing anyone ?)
3) it is more probable to success building simple and always looked-for product than something complicated. Advanced power supply unit is always interesting device for every electronician no matter how many and how good power supplies are already on his desk.
I wish you ( and am awaiting ) THE SUCCESS!
