Whatsminer P222C power supply main power circuit

The main power area of P222C is the voltage output terminal of the enitre power supply, which mainly has two functions: one is to output 14V for the hash board; the other is to output 12V for the control board. If several other circuits can work normally, but the PSU has no 14V or 12V output, the main troubleshooting idea is to check whether the main power circuit of the P222C PSU is working normally. Learn the specific circuit direction of this circuit through this video, so as to master the maintenance ideas.
