Hi All,
Because I was looking for a high voltage capability DC electronic load, I acquired a Tonghui TH8411. The overall build quality looks quite good and the software looks good too.
Firmware version is: 1.0.8,2.003 @ 2022 - 04 - 12
BTW I am experiencing some abnormal behaviour:
1) In the system setting menu I cannot cycle between "Source" CV an CC. CV is always selected
2) In Constant Power mode, the power set on the TH8411 has nothing to do with the power drawn from the DUT. It's much more lower and there is no correlation between the two.
3) In Constant Resistance mode, again, there is no correlation between values set and DUT behavior.
I tested the same DUT with an Array 3710A spare DC Load I have in my lab and it performs correctly in bot CR and CP mode.
Does anybody own a TH8411 and experienced the same?
Thanks
Danils
