Documentation
I keep my documentation for this equipment here:
- /home/jj5/electronics/equipment/electronic-load-ZKETECH-EBD-A20H/
To connect to this device via USB on 'verve' run EB Tester Software from the desktop. Use Device Manager and look for COM ports under Ports (COM & LPT) the EBD-A20H will be one of the CH340 options.
Purchase
Purchased from here: EBD-A20H.
Notes
The power supply this thing arrived with was 12V @ 1A but I'm using a different 12V power source.
