Safety note The A/C is being powered by a ST VIPER12A switch mode supply. This type of supply is not mains-isolated, so all voltages (even the low voltages) are referenced to mains voltage. Don’t work on this device while plugged in without being aware of the implications of this! Every metal piece, every wire, every component inside can be at deadly voltage potentials against mains earth! Don’t connect any mains-referenced measurement equipment (like oscilloscopes), as they’ll create a...
