Is it a good idea to get an all in one unit like this?
I looking for a new workbench power supply.
Variable AC/DC voltage and currents. Doesn't have to be real professional just for hobby/experimenting projects!
Thanks all in advance
chris
P.S. Do I really need AC? I thought it would make for a complete potential source voltage requirements, but now that i think about it I'm not sure!
Any thoughts on the necessity of having ACV as well?

i have similar one to that and does the job well for me when
fixing stuff and also need a psu to test my repairs as long
as you dont need more than 15V

Wow, fandtm666 MAX DCv out is only 15.0v?

I would not go for one that is part of a soldering station.
Standalone is best.
I have many that I use. Mainly self built. Silicon Chip or Electronics Australia based.
2 off Twin 0-30V Supplies @ 1.5A. These are two independent 0-30V Supplies in the one box. They can be connected to provided +/- Supply or A single 0-60V.
1 off Single +/- 0-20V Tracking Supply.
All based on the LM317 TO 3 Regulator IC.
1 off Commercial 0-30V Dual Supply that can be Independent, Tracking or Parallel with adjustable current limit.
They all have their uses.

Reschs, at first the combined unit seemed neat, but there are a lot of re-branded(named) units like the unit fandtm666 has, and they ALL seem to have the same controls, features, and most likely guts inside, just different vendor.
I also read on those units 852, 853 etc.bove, that they pose a fire hazard with the soldering/desoldering tools.
Between the fire hazard and the 15vdc max, will probably have me go to separate devices. Really how often do I need desoldering equipment, nice to have but I'll barely use. Also for some reason there are a lot of electronic devices here in the states that require a 24-28vdc source.
So a separate 0-30vdc/10a and a soldering station seems to be the front runner at the moment. Both devices below can be had for $63.00 USD.
But you guys (mates in Oz speak) are way more technical/electronic/engineering experienced than I am, so I thought to glean thru your advice as to which equipment is best.
Any more input would be highly appreciated !

AC isn't something I'd use a lot, but having a current limited P/S that delivers an accurate/stable voltage, right through it's current range is most useful. I've got a couple of different ones, one I built (0-30VDC fully regulated @ 5A with current limiting), a Integral Design 5020 ex military P/S (0-50VDC @ 20A fully regulated, with current limiting) and another dual 20V @ 5A with current limiting (from Jaycar I think). All useful for various different jobs, the big one I've even used for testing industrial welding wire feed boxes, that can draw about 15A @ 48VDC.
Variable output voltage and variable current limiting in a DC power supply are very good to have.
I past employer built a number of power supplies featuring variable voltage output (2.5VDC to 30 VDC) and variable (foldback) current limiting (200mA to 5.0 A) with separate voltage and current meters and I was given one for my own private use.
I have used it for many years now and found it to be an invaluable addition to the workbench.

im no techy, wish i was, & cant do any component level fixes
except swap parts thing
so do these scope thingies pick up motherboard problems etc?
i just have a few atx psu's, a variable laptop psu, a multi meter
a range of different mobo's, ram, cpu's

Yep, I thought he may have been confused is all. Actually philquad, another lowtech type of "scope thingie" is a Huntron Tracker. This device is used to compare circuits between a known good board, and a suspect board. It gives a visual display dependent on circuit characteristics. We used to have them in the RAAF, and they were pretty good for doing quick comparisons to determine if there was a fault on a board or not. I built an adaptor for a CRO, many years ago, that did a similar thing. It was mainly used for a quick check of components, to see if they were stuffed or not, but it could be used the same way as the Huntron Tracker.
Similar to this one:

Made a standalone unit from EA or SC circuit based on Huntron tracker. Used it about twice, found it f_&0$3kn useless.
There is a bit of an art to using them, and to be able to recognise particular displays. But you do need a known good board to compare with.
