New Siglent SPD4000X series power supply

[oewean]

Siglent has a new power supply, SPD4000X series.
Looks nice and well speced.

Video here:


Looks like only 2 of the channels are 32 volts.

Looks like they got the banana terminals finally spaced properly 

Seem relatively expensive compared to the SPD3303X-E, altho having 4 channels like the GPP-4323 is nice, as is remote sense on 2 channels

Best,

And it has a numeric keypad.

Is it made by GWInstek?

What kind of question is that?

They are both manufacturers.
Others rebrand their products, respectively....

A very logical one as Siglent and GW Instek have sold the same power supply before.

On second look I notice the USB-A is at the back instead of on the front. Who thought of that?

Seriously ?
I had no idea that was the case...
Which one?

As far as I know that is not so now...

Just curious, my apologies if it's a stupid question. It struck me as quite similar to the GPP range, visually speaking and in terms of layout. Not saying they are identical, but I wouldn't be surprised if they share the front-panel PCB, or use a very similar one.

Also, if I'm not mistaken, The SPD3303X-E shares at least the output stages with a GWInstek PSU, can't remember which.

I don't say that as a bad thing, I quite like GWInstek.

FYI
SPD1000X models use 19mm terminal spacings.

I too ask for qualification for this statement.

To date, none of the Siglent linear PSU's had a USB A port at all and this is a welcome addition to the range so to not need PC SW to update firmware and use USB external memory to store/load setup/config files.

No not stupid, I was just confused because AFAIK they don't do rebrands, other rebrand their products.. I'm not aware of any collaboration with GW Instek in that regard.
And yes,I like GW Instek too, very decent company and products.

The GW Instek GPD-3303S shares the same construction and the same output stage. And it wouldn't surprise me if this collaboration goes much further than this product. After all, GW Instek has a much longer history designing power products compared to Siglent. It wouldn't make sense re-invent the wheel just to satisfy NIH syndrom.

Looks like only 2 of the channels are 32 volts.

And 6A each.
SPD4306X looks the most interesting/capable model with two 30V 6A and two 15V 1.5A outputs which if can be seriesed/paralleled provides for a useful range of outputs.....
60V 6A or 30V 12A would be very handy for some.

Looks nice

Not for me, although I generally have a problem with the look of today's power supply units, which are becoming more and more overloaded and pop-colored.
The second point, which is not so interesting for private use, is the terminals.
At work, we only use 4 mm safety test leads, which don't fit in there.
No, for once I'm not impressed by a siglent product, I like the 4-channel from GW Instek much better, both visually and in terms of the connections.

Shrouded retractable ones ? 

[Antonio90]

The Instek is quite nice, although 33% more expensive than the equivalent Siglent (chinese MSRP)
Will any of the Siglent offerings operate on two quadrants as the GPP?

I have a GPD-4303S, which I like quite a bit except for the fact that it can only turn on and off all channels at once. I did burn a cheap 3v chinese scale with 20v by mistake thanks to that. Also, no numpad. This looks like a very good replacement.

[Martin72]

Shrouded retractable ones ? 

We have a few dozen of them as a temporary solution for our old devices without safety bananas(until they will be replaced).
I'm certainly not going to buy appx 300 new cables so that I can use a power supply unit with such terminals
In addition, these sliding sleeve cables are mechanically fragile and of poor quality, even though they come from Hirschmann.

Hmmm, never had such problems with the 100's we've supplied from Aliexpress. 

However we did get a sample shipment for assessment before bulk purchase.

We use them daily under partly rough conditions, not only to connect something that is on a lab table.

[temperance]

hm, keypad and 1 rotary encoder... So you want to adjust the output voltage on CH1. You turn the encoder and ooops, magic smoke. You just adjusted CH2.

I don't like those power supplies for generic daily use and prefer supplies with separate pot's or encoders for current and voltage for each channel.

[nctnico]

Typically I never use the encoder on a PSU with a keypad. Typing in the number is quicker and you can cancel before comitting the new setting.

Dwelling on these comments, I believe many instead will prefer terminals that provide connection options.

Generally the hobbyist prefers multiple connection choices and I certainly do as when I built my first PSU one of the must haves was cross hole drilled binding posts with banana sockets which is just what this new Siglent PSU provides.
This allows for plain wire, fork and banana connections.

OTOH your work you may have different requirements for outputs than the target market Siglent has catered for.

I don't understand why more manufacturers don't use these...

[NE666]

I don't understand why more manufacturers don't use these...

Yup, and note the sense terminals on the front panel too
