H801MPWD Board Description

H801MPWD Board Description

The H801MPWD board is an AC power board, consisting of an AC power unit and a monitoring unit. The board supplies power to the device and supports the lead-acid battery for power backup. The AC power unit provides overcurrent protection, output overvoltage protection, short circuit protection, and over-temperature protection. The monitoring unit provides comprehensive management for the power system and storage battery, and also provides certain environment monitoring functions.

Functional Specifications

The H801MPWD board supports the following functions and specifications:

  • Input AC voltage: -100 V to -240 V
  • Input AC frequency: 50 Hz to 60 Hz
  • Single-phase three-wire AC power input
  • Connection to battery backup power (-48V DC)
  • Rated output power: 400 W
  • Alarm monitoring
  • Battery low voltage disconnection; charge and discharge management of storage batteries

Technical Specifications

Please refer to "Power Consumption and Maximum Frame Size of Boards".

Working Principle

Figure 3-48  Working principle of the H801MPWD board

The basic working principle of the H801MPWD board is as follows:

  • AC input power is supplied to the board. After AC/DC conversion, the power is supplied to the system backplane at -48 V (adjustable).
  • The board supports battery input. The monitoring unit manages the charging and discharging of batteries.
  • The board communicates with the system through the backplane, reporting board hardware and electronic label information to the backplane.
  • The board supports communication with the monitoring unit through the 485 protocol to adjust voltage and current and report alarm information.
  • The monitoring unit manages lead-acid batteries.
  • The optical coupler implements the battery low voltage disconnection function.
  • The board provides power distribution checking and alarm reporting functions.
