DC-Load wanted(Siglent SDL1020X-E found)
<< < (5/11) > >>

After comparing the specs it´s only the measure resolution, nothing else.
And more power...Maybe. ;)
And with simple using three commands I could turn the cheapest 1020X-E(522€) into the most expensive 1030X model(1177€).
Sounds too good...Let´s check this before/after "tuning".
This time I ordered from welectron, I know the discount coupon by heart and it was also valid for this load.
So it is still just under 500(incl.VAT).




electr_peter:
FWIW, Rigol DL3000 electronic load series can also be modified easily (all models have the same HW) to get more power and resolution (color as well), instructions here dl3021-to-dl3031-conversion-discussion

However, I would not recommend Rigol load to OP based on requirements, because old FW with bugs has not been updated for very long time.

Yes, the only difference between the two models is resolution and power. There is no “maybe” as to the power upgrade, it definitely works to upgrade to 300W. I’ve done the upgrade to mine, and there are numerous videos of the upgrade being tested.

There is still the possibility that the hack only shifted the power limit upwards, or are there pictures of the inside of the 1020/1030 where you can see that it has the same hardware design?

I can't point to any photos offhand, but I've seen and read that they're the same. Many have done the upgrade and I've seen reports of tests to 300W.

And there's this post, although not accompanied by any photos, so you'd have to take their word for it (unless there's later photos, I haven't read the entire thread).

I just ordered a 200W and will be converting it to a 300W as my next project

Further I might later look at seeing what safety factor they are using on the main load resistors and upgrade the fan / increase the wattage beyond 300W but that will most likely be a winter project
