Would the switch on the transformer possibly be software controlled? (By software, I am wondering about firmware on a device reading a sensor, as opposed to a physical mechanism). I don’t know enough about the internals of these things, but I wonder if you could maliciously overwrite firmware, whether certain protections could be made to fail. I’m going to assume this kind of thing is likely covered in FMEA and such, so is unlikely.
