5.1 Power Supply RequirementsDC Power Supply RequirementsWhen the ZXR10 T8000 uses a DC power supply, the requirements are as follows:

l The power supply screen (meaning the power supply source) must supply powerstably and reliably. The power supply screen should be located close to the device,so that the DC power cable from the power supply screen to the device is as short aspossible. This reduces electric energy loss and saves installation costs.

l The DC power supply screen must comply with standards. The output voltage mustbe within the normal range of the device. The storage battery must be able to supplypower for at least one hour.

l If the communication capacity of the equipment room is large, or if there are devices fordifferent communication systems, multiple independent power supply screens shouldbe used to supply power for the devices, meaning scattered power supply. If severaldevices share the same power supply screen, the power supply for the devices shouldbe controlled at different levels through separate circuits. This prevents a fault on onedevice from affecting normal operation of other devices. The power supply capabilityof the power supply screen must meet the requirements for the situation when thedevices operate properly with a full load.

l The device operates in 1 + 1 redundancy mode, so an independent power supply forthe redundant devices is required.

l For a large-scale communication junction center, independent power supply systemscan be provided based on floors to supply power for the devices in the equipmentrooms.

For the technical parameters of the DC power supply, refer to Table 5-1.

Peak-to-peak noise voltage ≤ 200 mV.

Dynamic response The recovery period is less than 200 ms. The overshoot is smaller

than or equal to ±5% of the DC output voltage.

AC Power Supply Requirements

When the ZXR10 T8000 uses an AC power supply, the requirements are as follows:

l The AC power supply screen can supply power stably and reliably in anyenvironmental condition. Each output to the device meets full-load powerrequirements and derated power requirements.

l if there are devices for different communication systems, scattered power supplymode should be used.

l A TN-S power distribution system should be used in the AC power supply system.l It is recommend that the power of the device should be provided by two outputs of the

power supply screen for 1 + 1 redundancy.

For the technical parameters of the AC power supply, refer to Table 5-2.

Table 5-2 Technical Parameters of the AC Power Supply

Item Description
