The H801MPWD board converts AC input power to -48V DC output through AC/DC conversion. The integrated monitoring unit manages battery charging/discharging cycles and communicates with the system backplane via 485 protocol for voltage adjustment, current monitoring, and alarm reporting. The board also provides 3.3V power to the monitoring unit and implements battery low voltage disconnection functionality.
