Looks like they are copying Instek ...



I dunno who INstek are copying

[nctnico]

It wouldn't be the first time Siglent and GW Instek sold an identical power supply.

[rf-loop]

I can not see any kind of copy. Oh well USB connector and its symbol is same.
Both are made in China. Other is like from museum and other is bit more new technology.

@rf-loop

Hi - hope you are keeping well.

You forgot to mention - they also have the same rubber 'feet' - positioned at same offsets AND most importantly the power ON/OFF switch is in same location 

Seriously - it’s all a matter of definition of what is a copy.

Perhaps in China it’s not considered a copy is it’s not a 'clone' - i.e. an exact lookalike

In other countries - they protect their respective industrial designs - which encompass the general shape, materials used in the finish, colour schemes, layout of controls, alignment of front panel air vents, etc, etc.

Industrial designers are very fussy and get paid lots of $

A good example is Apple Computer - they pay a fortune to some guy / gal sitting in some jazzy office and sketching some  (what they consider) breakthrough concept in what THEY think is the next big idea on how the item should look.

With Test equipment - it’s probably not that extreme - but I guess some companies DO PAY lots of $$ to differentiate themselves from others and establish their 'mark' with the consumer.

It is very easy for many companies in China to simply 'skip' this step in the design process - and simply choose something which already is / has been established with a consumer.

A new product which sort-off looks similar - becomes 'easy on the eyes' and is likely to be less critical with the consumer - who is already familiar with something which has the same general features (not clone).

So like you said it’s not a copy - but is similar.

It is difficult to be innovative and make a NEW shape to challenge the traditional shapes of products - including layouts of displays / terminals / and buttons.

The danger here is that it might not 'catch' the acceptance of the targeted customer, BUT on the other hand if it does (slim chance) it will then become the 'standard' - so it will be likely that 'others' will then copy that design for the same reasons their design was copied.

So there are no winners here - except the consumer - who might get a new and innovative design if more companies refrained from copying existing industrial designs.

Just my opinion ...

Take Care & Be Safe

BTW ... the UK is about to be locked down (whatch the news - Boris will try to blame the people) TOTALLY as covid-19 is spreading like wildfire - R is reported to be 2.6 in London - but the government is publishing Average figure for whole of England of 1.4 - misleading the public like always (sorry - no politics , no covid comments - but I am angry!)

Hello RF-Loop

I have been meaning to ask this for quite a few months now.

Have you been employed by Siglent to design any of their products or a subsidiary thereof or a consultancy company outsourced by Siglent in the past? your knowledge of their working practices is most intimate and in depth.

[bd139]

They ripped off Kikusui by the looks

[nctnico]

https://www.kikusui.co.jp/en/product/selection.php?Category=DC%20Power%20Supplies

But oddly enough some GW Instek PSUs have the exact same dimension as the Kikisui power supplies. The same for electronic loads from GW Instek and Kikusui which are nearly identical both in physical appearance and specs. In the end it doesn't make sense to re-invent the wheel for a relatively low-tech product like a power supply or dc-load so outsourcing the design to an OEM makes sense.

[bd139]

Yep 100%. Unless that OEM is Mastech 

[nctnico]

Yep 100%. Unless that OEM is Mastech 

That is also possible. Tektronix has some similar PSUs (specs & look) under the Keithley brand. It is definitely teardown time 

[tom66]

Having the same form factor probably makes it easier to sell to customers who have these in racks.

[maginnovision]

The thing that strikes me as odd is the 1080W output. As far as I've been able to find only instek has that specific power output.

Yet this can backfire on you. GW Instek used to be the OEM for another manufacturer of test equipment; let's call them Manufacturer X, based out of X-Land. (I probably shouldn't name them as this relates to my day job; you know how that goes....) Manufacturer X's units were marked Made in Taiwan rather than Made in X-Land. Fast forward 15 years. Now both GW Instek and Manufacturer X are active in this small market segment. But X's new units look nothing like their old units, and are now Made in X-Land. And a new GW Instek unit and old Manufacturer X unit are, if you take off the lids, quite obviously related.

So OEM relationships can get quite complicated!

Models of 40V 360W, 80V 720W and 160V 1080W
CV, CC modes
Series and parallel output capability for dual and 3 channel models.
LAN and USB connectivity.

What good is a power supply without terminals for the output?

[bd139]

System power supplies tend to have the connections on their butt rather than their face. Not everything is a "bench" supply.

[Elasia]

Interesting addition, been looking for a high volt / amp unit for the house for ages now but always cheeped out.. wonder if it will cost the same as the gwi

As far as connections, due to how many amps it can handle, they use lugs.. as far as why always in the back vs front? safety thing has always been my opinion.. that said if i get one i'd for sure bring the connections to the front with some thick copper wire and put into some kinda lug terminal assembly or other high amp plug

[tautech]

Certainly this is the case as more info is now available.

Many times new product release prices to the west bear little relation to official Chinese prices. 

[Elasia]

What do you think they will come in at? I do got my eye on 2x SPS5083X since you can link them.. i figure the 1080W versions will all be around 2k usd which is inline with gw pricing

https://www.tequipment.net/InstekPSW80-40.5.html

I do like that they can step power waveforms as well.. usually need something more like a chroma for that

[nightfire]

As Fluke, Tektronix and Keithley belong to the same company empire, and Keithley is officially referred to as "a tektronix company" it is expected behaviour that some products are quite closely related- same with big car manufacturers, where the different models share lots of stuff from a central parts repository...

[Elasia]

A manual and quick guide are now posted, after reading it over think I'm going to buy two of SPS8053X like i originally thought.. i was kinda hoping that maybe the triple output standalone could be combined with another but sadly appears to just be 3 of the smaller single units put together.. cant serial all three channels either, only two just like a bigger standalone master/slave.

Be tempted to get them direct from NA but suppose i should just wait and get the saelig discount, either way i'll open one up like i normally do and take some eyecandy pics eventually

Also of note... since these are all hardware different.. nothing to hack really

These should be on sale sometime in mid/late January for NA from what the local office just told me 

They are already on tmall for sale as well from utest
