There is a nice review/overview https://www.youtube.com/watch?v=BhZgVdVELJU Also recommend to read https://www.eevblog.com/forum/testgear/et5410-or-dcl6104-or-a-third-programmable-electronic-dc-load-in-the-budget-cat/ Few notes/comments: - fast delivery (2 weeks over Holiday season, standard EU shipping for 23 USD) - great LCD, excellent viewing angles (no color changes from angles) - it is louder than necessary/ I would like but unfortunately most similar instruments are. Probably in a factory/lab does not matter but in home is annoying. But could be modified (see the link above and/or fan changed; it is a standard 80mm, 12V fan) - no indications when it can't regulate any more (e.g. in CC when the source cannot deliver the set current) - FW could be improved, but it works - perhaps the only / the biggest concern is the manufacturer support: ○ You can download user manual from http://www.czdingchen.com/custom/2 but it is only in Chinese (ok, Google translation helps here) and outdated (version 1.0, printed manual which came with the load was 1.1). ○ SW, drivers, etc only on Baidu disk. Requires Baidu account which I was not able to create. I have yet to try to sort this with the vendor/manufacturer. Eventually there might be some 3rd party / opensource (see EEVblog forums). ○ Question of FW updates. The load has front USB connector for FW updates but have not found any publicly available updates. Btw my load came with version v02.06.01.08. Overall very nice programmable DC load. Nice and solid build, in general I would recommend but beware of the support uncertainty.

  • roberus Hi,I'd like to ask you, is it possible to test symmetrical output of power supply, if I have i.e. /-50V? I hope output 1 and 2 from the device can be merged (one black and another one red pin). Please let us know. Thank you very much in advance. Robert
