Application scenario of the H831PAIB board

H831PAIB is an AC power board with backup power. It converts the 220 V AC or 110 V AC power, outputs -48 V DC, +12 V DC, and +3.3 V DC to the backplane and, through the backplane, powers the service boards, control board, and fan monitoring board. The H831PAIB board also supports lead-acid or Fe-lithium battery power. If the AC power supply fails, the battery is used to supply power.
