H901PISB Board Description
The H901PISB 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.
Feature and Specifications
The H901PISB board supports the following features and
specifications:
1 channel of 220 V AC or 110 V AC input
Rated output power: 600 W
1 battery for power backup
Input overcurrent protection
Input power monitoring
Temperature query and high-temperature alarm
Parameters
Board Parameter
You can query power consumption, weight, maximum frame size, and
normal operating temperature of all boards.
Table 1 lists the power consumption, weight, and maximum frame size
of boards.
The operating temperature of H901XSED and H901TWED is -40°C to
+55°C (in MA5800–X17/X15/X7) or -40°C to +65°C (in MA5800–X2) and
the lowest board startup temperature is -25°C. The operating
temperature of other boards is -40°C to +65°C and the lowest board
startup temperature is -25°C.
NOTE:
The power consumption of a board is calculated based on the
following conditions:
Operating voltage: -53.5 V DC.
Ambient temperature: 25°C.
Static power consumption: All ports do not carry any loads and
optical modules are not installed on optical ports.
Maximum power consumption: All ports fully carry loads.
The board power consumption slightly varies with the power module
configured for the board and discreteness of components.

| 220 V/110 V AC power Battery connection terminal Battery temperature sensor port |
| Battery loop module: detects battery current. Protection circuit: protects the components in the circuit. Filter circuit: filters the DC power in the circuit. Voltage converter: converts high-voltage DC current to 48 V DC
current. Detection circuit: checks the protection fuse for any faults and
detects power input and the board ready status. It reports the
detected results to the control board through the backplane. Backup power management circuit: manages battery charge and
discharge. |
