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:
