exceeds –10% to 5% of the rated voltage, or exceeds the permitted voltage
range of the device. We should adopt the voltage regulator to meet the
requirement.
�
It is required that the AC uninterruptible or transient communication load
should adopt the UPS power supply system or inverter power supply system to
provide power.
�
When the AC becomes abnormal, to ensure the important communication load
and important power load, the telecommunications site should be configured
with the generator set as the self power supply. The capacity should be no less
than 1.5-2 multiples of the total capacity of the AC uninterruptible powered
device.

The DC power supply mode should ensure stable and reliable power supply. The
power should be deployed near the device to ensure the DC feeder line as short
as possible. The requirement for the DC power is shown in Table D-6:
