content: Interesting find. I also ran into this DC load on amazon today too. It looks like it may be based off the itech design, but I can't say for certain. The entire front panel looks completely different and the rear panel has usb and ethernet - not found on any other dc electronic load of this size. Ethernet is not present on the Bk precision, itech, mayuno, Applent, Array/Atten or Tonghui units. This is definitely an interesting unit. I wonder if anyone has one?Here's the ebay listing from the same seller:https://www.ebay.com/itm/132760029322

content: Some more info:The Korad website seems to be down or gone, which does not instill confidence.KEL-103 manual with specifications. The specs are very close to the BK 8601.https://www.sra-shops.com/docs/srasolder/instructions/kel-103_user_manual.pdfIt looks like this KEL-103 is identical to the TENMA 72-13210 dc electronic load sold by farnell:https://uk.farnell.com/tenma/72-13210/dc-electronic-load-prog-30a-120v/dp/2848407https://www.farnell.com/datasheets/2602709.pdfHowever, it looks like this is a very un-finished unit:https://www.element14.com/community/thread/64903/l/need-windows-usb-driver-for-tenma-72-13210-electronic-dc-load-30a120v-300wI would love to see a teardown of this unit regardless!
