TA-0376: UNI-T UDP3305S-E Programmable DC Power Supply Linear - Hands-On Review 

Looks pretty good really, even I’m tempted to try and get one to replace my 3 channel Korad

Nice device Tony, I have a slightly worse UNI-T UTP3305-II, but it's good enough for me and I'm happy with it. Thanks for the video and may it serve you for many years.

Super interesting... And Christmas is coming... I'm thinking about it. Thank you Tony for the always interesting videos...✌

Your video is just in time, shopping now and I'm hesitating between Rigol dp832 or dp2031 and now this uni-t for the price looks very well. Thank you!

Thank you, Tony. Another comprehensive review - much appreciated. Nice looking unit and the zoom feature is a great idea! It is a shame the software doesn't detect the NI-VISA drivers correctly, overwriting the new version with an older one can really cause problems. It looks like there is a USB port on the front panel as well as the rear panel. Regards, David

Uni-T has really been stepping up their game. And it's comparatively priced to 50 year old one's on ebay! 👍

Very nice, went ahead and ordered one, Amazon has it and a 20% discount to boot! Thanks for helping me spend some $$ Tony!

Nice review. I agree with your impressions. Just need GPIB and four-wire sensing. It would be nice to measure its ripple. I'm still happy with my old PS2521G.

Thanks for sharing your review. Apart from the little hick-up with the driver install, this otherwise seems to be a great PSU. Hope the ripple will be small. I actually have ordered the UNI-T 3305S-E from Eleshop today for myself :) as I like to get rid off my several small and cheap-ass PSUs of which I have 4 or 5 devices flying around my lab. I also have the big Aim TTi PL303 QMT-P a full-blown triple PSU which has only knobs to adjust voltage/amps "freestyle". It is my most precise and expensive PSU indeed, but nothing to quickly carry from one workbench to the other when I am working on my different projects ... so, the UNI-T will complement my equipment properly. I very much like the possibility to enter numbers directly on the number key pad of the UNI-T. I have also the Siglent PSU since 3 years or so, where you always need the arrow keys (fine) to change position digits left or right and the knob to adjust and change voltages/amps values for that selected digit - still feels odd. Typing just the number + enter is pretty convenient ;) The Zoom mode of the UNI-T comes in very handy for having visually bigger numbers to better see. Like that! I also love the fact when either in serial or parallel mode, the display always shows the total voltage/amps. This is so weird with my Singlent PSU (as you showed also) where you just see "half" of the voltage or amps in the display when coupling the channels. However, the Siglent did a fantasctic job so far on my work bench, but this new Unit-T device will be doing alike as good on my other workbench ;) ...

Nice Tony....I only have one device from this company...it was High voltage meter, i use to test our x ray units high tension cables, i did not know that grew so fast to have all sort of devices now....i was honestly looking to buy the 4 channels INSTEK power supply ...hmmm

Heloo Tony. Perhaps it would be good to show how a multi-channel laboratory power supply can be connected as a balanced supply (+12V) : 0 ground : (-12V). Connecting two channels in series does not seem to create a zero point for the positive and negative voltages. I believe that this is possible by connecting (A-) and (B+) separate channels and thus creating a zero potential for both the positive and negative voltage branches. It is good to connect the zero contact to ground (in both channels of the source). It would be good to have a short video on how to connect it and how it works. There are several videos on RU-vid about wiring two separate sources as symmetrical. I think that both separate channels of one source should work exactly the same.

Interesting unit for sure. But when you put it in seriel mode, as in 30 + 30 volts, do you then have access to the midpoint, so you can get -30 - ground - +30 volts out of it? To drive something that needs both negative and positive voltage.

Hey Tony, dit is een mooie lab power supply met een goeie prijs. Mocht je niet een teardown doen of tenminste even binnenin gluren?

Does it do dual rail power for like opamp powering. In serie or normal mode with the center plus and minus connected?

Thanks for quick review! Could You please test OCP function for different current setting? It's not switching off output for me when I set 1A/1A output/OCP and add simple resistive load that is connected all the time. Even when I short outputs. Monitor function works, but it takes few hundred milliseconds to switch output off.

I have the same and I’m very very happy with it. Hey Tony the zoom option is missing on mine.

Hello Tony, tell me please, if the unit remember the last voltage and current settings after power off and power on.

Any chance showing the world the internals ? There is no teardown video so far (1/2024). I am very interested because I can't decide between this one and Rigol DP832.

Wow! It looks like this power supply is made to automatically be setup to test devices in conjunction with other test equipment devices? 😎 Thank you Tony. Amazon $519? UNI-T UDP3305S Programmable Linear Power Supply 4 Channels 328W 0~30V DC 0~5A

👍

Hallo, Which power supply is better in your opinion? reliability, stability? Unit-t udp3305s-e or siglent SPD3303X-E?

I am very tenpted to get this one. Do you know if it is possibe to get -0+ on the ouputs?

Nice, but not cheap. By the way, you can get therapy for test equipment hording.
