This is an interesting thread for me, as i am in the market for an electronic load. it is for home/hobby use, so my budget is limited, and i cannot stretch to a "genuine" Itech or BK load. The Maynuo range had caught my eye, and they can be had on ebay (for the spec I want - >300V DC rated M9712B) for about GBP£470, landed.
The two products are indeed so incredibly similar, that I am prepared to believe (as BK appear to have confirmed) that the Maynuo is a pretty direct and simple-ish copy, albeit with a more detailed display. Maynuo must have had access to the original microcontroller source code, and recompiled it for a different display. The specs are very similar, so I am now left wondering whether the Maynuo does perform to the quoted spec, or they just copied the spec sheet, too!?
VERY little info about on Maynuo, but I did find this
. It seems to exist, and work (not an in-depth test, but prrof the device is out there)
I have looked at cheaper Beich and Array "brands" of electronic loads but I suspect these may be "slower" to react to load changes. Also, markedly poorer (if still not actually poor) accuracy quoted for these.
And yes, Maynuo loads appear in ATTEN variants, too. No doubt about that.
If I do land one (in final negotiations with the Financial Controller at the moment!), I will of course "do a Dave" - Dahnt turnit on, taykit apairt!
Oh, and I think Joy at MCS would like me to confirm her gender. Definitely a lady of the female persuasion.
