PAIB (dual power module)

Description

PAIB is an AC power board with DC backup power support. This power board converts 220V or 110V AC power to -48V, +12V, and +3.3V DC, and then uses the backplane to deliver power to the service boards, control board, and fan monitoring board. Also, the PAIB board uses the battery input (lead-acid battery or lithium iron battery) as backup power, and when the AC power supply is interrupted, the PAIB board switches to the battery for power supply
