Thoughts on GW Instek GPD-3303S?

[whyme?]

Hello,

I'm in the process of building a small electronics lab and am shopping for a bench PSU. I've come across the GPD-3303S, a gentleman is selling it for $300 CAD (roughly $225 USD). Is the price reasonable ? It looks like a good bench psu and Instek makes solid products.

What I will be using it for: mostly for educational purposes, basic circuit analysis, building rectifiers ccts, mosfet ccts analysis, Arduino stuff and may be some design projects in the future.

I was checking out the popular but modest KORAD KA3005P as a potential buy but perhaps an used psu with more channels could end up being very useful. I can acquire the Korad for ~$250CAD.

There's also the BK1671A-ND for around ~$225 USD but meh.

What do you guys think ? I'm open to suggestions! Thank you kindly :]

I've recently been psu-shopping as well and that was one of the models I considered. Be aware that the newer 3303s units (if there's no gap between the binding posts for the 3 channels on the new ones) seem to have some overshoot problems and possibly poor transient handling on the 2.5/3.3/5v third channel.

As far as I can tell the main 2 channels are fine though, and if you do get an older "gapped" version all 3 channels are good.

For that price I'd spend a little bit more and buy the newer GW Instek GPE-X323 brand new with warranty! At least this model has individual channel controls.

The thread about the possible problem that BMCha is making reference to can be found here:  https://www.eevblog.com/forum/testgear/instek-gpd-3303s-power-supply-overshoot-opinion-wanted/25/

Also, http://canada.newark.com/ sells the GPD-3303S for $700 (plus sale taxes)... so a nice used one at $300 is probably a good deal.

yay, got it for $270 :]
I'll do some tests to see if it has this overshoot+transient issue

Any word on the overshoot? I'm looking at this power supply as well but leery about the overshoot.

Hi, does anyone of you encounters a problem with GPD-3303S that is limited to 4.5DCV in both channel 1 & channel 2?
