Sanden PET-07 Power Supply RS-232 Module Reverse Engineering – Part 2

Sanden Title 2

In this video we take another look at the RS-232 plug-in module for the Sanden PET-07 CC/CV power supply. In particular, we see how the voltage output can be controlled and how this clears up some ambiguity with the circuit design. In part three, we will *finally* attempt to communicate using RS-232 to monitor and […]

Sanden PET-07 Power Supply RS-232 Module Reverse Engineering – Part 1

Sanden Title 1

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. […]
