| BradC:
With a view to testing some custom battery charging profiles, I bought one of these as it has a PC interface and frankly was cheap : https://www.aliexpress.com/item/1005005060176198.html It doesn't come with software, and I've been unable to locate any. I've messaged the vendor through Aliexpress. The USB interface presents as a standard CP2102 USB to UART Bridge Controller. I've tried a few different baud rates and random SCPI IDN commands. Does anyone have a lead on software or a protocol? |
| BradC:
The vendor got back to me. They provided Windows drivers, the PC software and a neat little docx file that "documented" the protocol. Winner. When I get a moment I'll post them somewhere. The archive is ~250MB. Haven't even bothered to install the software, just knocked up a bit of python to control the supply. For a fully controllable 30V/10A PSU for less than $150 landed, I'm quite impressed. |
| BradC:
I got a private poke about posting the doc, so I dug it out. I've been using this to talk to the PSU for a while now, so I can verify it works. There are some idiosyncrasies when measuring voltage as it approaches the changeover from CC to CV mode where the voltage will appear to leap about 30mV instantly. To measure an applied battery voltage, I set voltage to 1V and current to 0A. |
| PlainName:
Can it output max current at max voltage without melting? |
| BradC:
Dunno. Haven't got a big enough load to test it. I've tested it for a couple of hours at 200W and it didn't flinch. |
