H902PISB Board Description

The H902PISB 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 or iron lithium battery for power backup. The AC power unit provides overcurrent, output overvoltage, short circuit, and over-temperature protection. The monitoring unit provides comprehensive management for the power system and storage battery, and also provides environment monitoring functions.

  • 220 V/110 V AC power

  • Battery connection terminal

  • Battery temperature sensor port

  • Iron lithium battery activation port



  • Battery loop module: detects battery current.

  • Protection circuit: protects the components in the circuit.

  • Filtering circuit: filters the DC power in the circuit.

  • Voltage converter: converts high-voltage DC current to 48 V DC current.

  • Detection report circuit: checks whether the protection fuse is faulty or whether the power input or board is detected, and reports the results to the control board through the backplane.

  • Backup power management circuit: manages battery charge and discharge.
