Huawei PRTE | OLT Board | 1 x 48V power

H801PRTE is a power supply board for OLT devices such as MA5683T and MA5680T with -48 V DC for the device.

The H801PRTE board supports the following functions:

• One power consumption -48 V or -60 V DC (input voltage range: -38.4 V to -72 V)
• Filtering and limiting current for power input port
• Detection of under-voltage, detection if input power exists, and damage detection
• A combined protection alarm reporting and online disc signal reporting
• The ALARM indicator

• H801PRTE has a 3V3 power supply connector that leads a -48 V or -60 V power channel. After passing the protective circuit and filtering circuit, the power supply is transferred to the mounting plate and supplies energy to other plates in the service rack.
• The detection and reporting circuit detects fuse damage. Detected signals and board presence signals are reported to the control board of the same channel. The LED displays status.
• Detection and reporting circuit detects under-voltage of input power and whether there is input power.
• The 5-volt power supply from the backplane is used to supply power to some circuit boards.
