I have a question. An IP camera with PoE power supply is available. On the board the transformer PDT2431SR on a datasheet, on contacts 3/4 power supply of 33-57 volts, contacts 1/2 is 12 volts, contacts 5/8 and 6/7 is 5 volts. So that's the question if I immediately apply to the contacts 1/2 power 12 volts? Will it work?
