content: Help me decide!I like the lower price and upgradability of the SDP3303X-E (making it an SDP3303X), but I really like the idea of direct input on the Instek GPP-4323 (LAN). The extra channels on the Instek are nice plus as well. But I don't see nearly as many people here using the Instek as the Siglent. Should I take that as a bad sign?Has anybody used both and have a strong preference? Are there any gotchas with one vs. the other that I should be considering?

content: Quote from: pcee on September 30, 2021, 03:38:04 pmNo. The Instek GPP-4323 is much newer. I'd get one if I needed a bench PSU right now. A couple of years ago I ended up with the Keysight E36313 because neither Rigol or Siglent offers a PSU which really ticks all the boxes. On a digitally controlled PSU a keypad to punch in numbers is a must as well as having truly isolated channels.

content: The Instek works great for me. It's also smaller then most people expect. For example my AIM-TTI QL355T is much bigger next to it. The AIM produces fan noise while the Instek is silent (except of course under heavy load) and i enjoy that more than i had thought. I don't like how some of the specialised functions are implemented in terms of the GUI, but i use those rarely anyway. As has been said, the supply has a keypad and that is mandatory for me as well. The internal series/parallel switching is a nice touch as well as the dc load function (although i must admit i haven't used that function yet). The display is decent. I would most certainly buy this supply again.

content: The GW 4323 is much newer.And you dont have members like Tautech spamming the whole forum with that other brands posts.I am sure you better buy the 4323 and not that other brand.I dont ever buy anything of that other brand, Tautech ruined it for them.The quality is better from GW i am sure, no reason to buy that other brand.Buy what is new, you dont want a channel is that not current-limited that could blow up your 5volt section.The GW have all 4 channels current-limited.

content: Thank you all for your help! Instek it is. I just needed the encouragement to spend more money.One question on power supplies, though, applicable to both: what is the usefulness of specifying a voltage or current down to 1mV/1mA or finer when the accuracy is only specified to within 0.03% + 10mV / 0.30% + 10mA?
