Hi Gene,

I looked into the sister model a while back and the issue was no documentation for SCPI which was a deal breaker for me. I don’t know if that has changed. The thread is here: https://www.element14.com/community/message/298715/l/kel103-scpi-programmers-manual#298715

The multicomp DC loads are very similar to other products on the market (like the Kel103). I did find some communication protocols manuals from a similar model (very likely the same protocol). Here is a link to the site with the manuals.

There is a download for "Communication Commands with Computer.pdf" which looks like what you may have been looking for.

Thanks everyone for the comments. Once I started looking at some of the other clones of this design, including some really bad reviews (lots of DOAs), I decided against trying out this product. Instead, I found a used B&K 8500 on eBay that I was able to get on a best offer at a pretty good price (with a good return policy and ebay's buyer support). I will let you know what I think about the purchase once I get some experience with the new device.

Not sure how close of a relative it is to a Korad product rebadged - but I was trying to help out someone with a Tenma rebadge and that one was a bit of a head-scratcher using UDP ... Re: Need Windows USB Driver for TENMA 72-13210 (electronic dc-load 30A/120V 300W)

That is a good find! The reason I have been reluctant is that I have had mixed luck with Multicomp instruments and SCPI. A power supply I bought didn't have the SCPI documentation on the Newark site but I was able to figure the commands out by trying various common commands for power supplies. Gough Lui subsequently found a rebranded supply like mine which confirmed the commands I had sussed out. Then I purchased my Multicomp LCR meter and found that not all the commands in the manual work and some that do are intermittent and not reliable. I've not had any problems with the other instruments.

However, that DC load is priced very well, and should you find it works well I'd be interested to hear as I am still in the market for one.
