In this video we take a look at the Sanden PET-07 CC/CV power supply. In particular we look at the RS-232 plug-in module and attempt to make sense of the signals between the main board and plug-in board.

In part two, we’ll apply this knowledge to attempt to receive RS-232 data from the power supply.

If you have any information or documentation for the Sanden PET-07 power supply, please let me know!
