Is there a better power supply option for $700?

I know that this statement was written in bold, but I would urge you to reconsider. High quality used power supplies are fairly abundant in the USA.

hi JJ_023,
sorry about my previous post... :-+
"Electronic" is a like a so large field of grass, that people who deal with issue "x", can't see people who deal with issue "y" over the horizon... cause this field is so so large

I'm pretty sure that, b4 posting, you've "plowed" (direct translation of french slang, not sure it is the right equivalent in english, but you see what I mean :) ) the web to find the product that fits your needs (x ouputs / A @ output / V range etc....), reviews here & there to get info vs reliability (given the price & given it is a heavy duty device, reliability over 3yr min is a minimum.
The product you find has a load function => cool !

I see what you mean, no brainer, fine ! :-+

Markal sells a paint marker specifically for oily metal that basically writes on anything and is very tenacious. Sometimes it's difficult to get off even with acetone. The downside is it takes a little bit of time for it to dry which makes it very prone to smearing. Long time being roughly 5 minutes.

Nice! I'll file that away, it sounds useful.

One thing is that you do need proper lab psu. More than one, isolated from each other.
Other thing is what kind.
You won't need network connected smart PSU most of the time.
Most of the time simple analog one with potentiometers is good enough.
You can have several single channel ones instead of one multi channel.
You want a smart one with LAN and SCPI only if you want to write scripts to automate it.
Also some multi channel PSU have weird channel combinations. Instek GPP-4323 has 2 channels with full capacity but 15V and 5 V have only 1 A capacity. Some will argue that it would be more useful to have 3 full capability channels instead..
It all depends on your needs.

hi Veteran68,

as I said on my previous post, "electronic" is a very wide field...
but you said is more "electricity" stuff than "electronics"
to me, "electronics" relates to "PCB level", thus V=<3.3VDC roughly...
I'm a young player in EE, but from start I found strange that people dealing with EE deal with V>5VDC (OCXO with Vin=12VDC are over the place, but are old-stuff).
stuff.

But if you do any sort of repair or troubleshooting of consumer electronics, you're going to need more than an ultra-low power supply pretty quickly.

- breadboard => noise => no go
- battery as PS : => noise & sluggish vs transients => no go
- consumer electronics => 5/9/12V input (box), but then, inside the box > you got the input V down-step to match the PCB level => 3.3V or less... and so so..
Sorry about all my blabla
I just pointed out that "PCB level" is fun because it's |O and then you overcome the issue => go to the next |O ... I love that.... :-DD
To anyone, enjoy '24 ! lot of fun etc ! :-+
