New Rigol DC PSU's

[tequipment]

Yes I would be.  PM me.  I need a little background.  We are always looking for an HONEST!! review.. Dave has the best ones.. but sometimes I like to have products put though some additional testing..

[KedasProbe]

Someone received it yet?

I'm looking around for some (extra) PPS lately:
I like the DP832 specs but I have two problems with the DP832
- Red display will be hard to read. (why not just white!)
- Very deep mechanical design over 41cm, it will stick out too much to be practical

(1mV/1mA resolution key adds 71 Euro to the 304 Euro  )

I'm looking at this more expensive one instead because of that

edit: also is it just me or is it weird that the + terminal is put on the left side of the -

I think you can change the color to red, green, blue and white.  If you go to the Chinese website, you can download the user manuel and there is a menu that says "Color theme" and show the colors that you can change to.

At least that is how I interpreted.  I too was worried about the color red.

Yes, I see it also now, choosing white instead of red seems to be possible.
They should fire the guy who decided to use the red setting for the product pictures!
Although they also seem to have made some (acceptable) green ones.

Now the only thing I still need is a hole in my wall

[rbola35618]

Yes I agree, they should fire the guy.

If I can select this color is only setup what I will use.
(perhaps it can be just small amount more "amber".)



This display color has many ergonomic advantages. Therefore, this type of color scheme is also used in many demanding applications. But why they all do whjite front panels.  Where they have forget example these old HP equipments nice fron panels.

Display  tells also that even some design peoples in Rigol are clever and there is least one designer who is not "blue led fanboy".

But this front anel layout is "do not come to my lab"
And  also
+ (left) - (right)   may I ask Why?

Then, (I do not know but only this image)
Are these terminals really "standard" distance from each other. Or is it "rigol" special.

Are these terminals really "standard" distance from each other. Or is it "rigol" special.

It looks like standard 0.75" spacing to me. Maybe you think they look more separated, specially the ones far from the center of the photo but that's the parallax effect.

[olsenn]

My guess is that Rigol corporate had design requirements that the engineers were contractually bound to; one of which stated that the DP832A model must be in some way psychically different from the DP832 (without the A) even when the DP832 has all the extra options enabled. Without the different screen firmware, and the stickers on the front to correlate each channel to its specific colour, they would have been the same.

I guess there's only so much you can do with a power supply.

[berk98]

Hey guys, I just received my DP832, and I can answer some questions.  Yes, the binding posts are 0.75" spacing.

Also, the display color can be changed. Luckily, there's white which looks much nicer than the others.  Interestingly, the only place I can find that has more than one color shown at the same time is in the theme selection.

The buttons and menus are a bit difficult to navigate at first, but it feels rock-solid which totally makes up for that.

I'll probably do a review sometime, but I am quite busy these days.

[rbola35618]

Hey,

I got my DPS832 yesterday. I will probably do a first impression on the supply.
I prefer the green screen.

My DP832 is due to arrive tomorrow, looking forward to it!

Interesting thread, will keep an eye on the reviews to appear up here ;-)

Hey guys, I just received my DP832, and I can answer some questions.

Hey, can you confirm, that PS is indeed so ridiculously deep (41cm)?
Can these gray rubber corners be removed?
Can you measure real depth of bare case, not taking into account front panel connectors and these rubber things?
DP832 looks like real bargain for $400, but my bench is only 32cm deep
Any comments on fan noise? When used at home, fans can be really annoying...

Overall, after watching photos for 10 minutes, I start to like the design 
DP832 looks even quite professional with monochrome UI and all the buttons being grayish.
But higher models - that's just sad ... It looks like they have fired industrial designer who developed DS2000 series, and they tried to replicate this style by themselves
Especially function buttons under display looks out of the place...

[WBB]

Especially function buttons under display looks out of the place...

Those look like perfectly placed soft buttons. It's that keypad/knob layout that looks like a train wreck.

I was talking about shape / color, not placement / usability

Good point. I was looking at the usability aspect, which that keypad is not. With a keypad like that, I'm surprised they didn't put those soft keys on the back panel. Kudos for making those useable.

It is quite ridiculous, yes. Second only to my full-size rackmount multimeters.

Can these gray rubber corners be removed?

The rubber corners can be removed.  A couple screws hold on each of the front ones, and one on each of the back ones.  All metal threaded inserts, too!  The unit itself doesn't have any rubber feet, though.

The depth of the bare case is about is about 38cm.  Add 2.5cm to the front for the binding posts, and about the same to the back for the power connector.  At least in the US where I bought mine, the IEC connector is right angled, so you can scoot it right up against a wall or something.

Actually, the binding posts stick out further than the rubber corners.

Any comments on fan noise? When used at home, fans can be really annoying...

Fan noise is actually somewhat annoying. Nowhere near as bad as most of the cheap power supplies I've seen, but definitely a bit louder than my Rigol DS1052E, which I'd probably rate as on the verge of annoying.  Its also much more of a hum than a whirr, if you know what I mean. The fan does seem to be temperature controlled, but it doesn't completely turn off with no load.

Design certainly isn't bad.  There are a handful of quirks about the UI which I wish Rigol would update/change, but its easy to get used to it.  It also looks much more professional without the rubber corners.  It's too bad your bench is too short, because I'd definitely recommend this as a decent programmable power supply, especially for the price.

I’m thinking of getting the DP832, but I can’t tell the difference between the DP832A and the DP832? The only thing I can tell is the OVP and OCP increments, otherwise is there any other differences?

Did you check the GUI? and the options are already included.

[manticore00]

My DP832 arrived yesterday and I generally like it but one gripe I developed quickly was the circular arrangement of the number keys, it's just not intuitive at all.

I can't answer your question, but nice to have you aboard fellow OSS brother.

[lkftwin]

I am interested in this supply... but I only have limited money, so the 832 is much more interesting.  I DO note that on Rigol's site: http://www.rigolna.com/products/dc-power-supplies/dp800/dp832/ under the Accessories tab, you can purchase the hi-res resolution (1mV/1mA) upgrade for $93 and the screenshot is in full color.

Interestingly, everyone is saying that the display on the 832 is monochrome.  Obviously not, as berk98's photo shows!  The default *GUI* is monochrome, but obviously it's a multicolored display.

It seems likely that the 832a is the same hardware as the 832 minus the software upgrades.  That being the case, I wonder if the high resolution upgrade "enables" the full color display.

[rbola35618]

No it does not. I have the 832with the 1mV option and the screen is still one color. You can select between orange, green, light blue, or white. I chose the green color theme.

[Uup]

The hardware is most likely the same between the DP832 and the DP832A. Hardware wise, the 'A' version comes standard with RS232, LAN and digital I/O, rather than being options. The high resolution mode is likely just something activated via a key/firmware, rather than a hardware change.

I ordered a DP832A a week ago and should be getting it in the next week or so. I can post some internal pictures of it and do a mini review, if there's any interest.
