典型使用场景 |
|
BBU室内放置，直流供电场景。DCDU-12B可给BBU、RRU集中供电。 |
DCDU-12B 提供10路空开，使用10个快插端子，可支持现场做线。6个大快插端子支持2.5~10方电源线，4个小快插端子支持2.5~4方电源线。
DCDU-12B支持1*BBU+6*RRU+1*FAN或4BBU+1*FAN供电，超过3个RRU需要2路16方输入，具体参见附录1。
对于两路空开并联为同一个DCDU-12B供电的情况，需要注意以下几点：
- 两路空开必须是由同一个电源系统输出。
-两路空开的规格必须完全一致（包括空开大小、型号等）。
-两路输入电源线的规格必须完全一致（包括电源线长度、线径等）。

Typical usage scenarios
BBU indoor placement, DC power supply scene. DCDU-12B can supply concentrated power to BBU ａnd RRU.
DCDU-12B
provides 10 channels open, using 10 fast plug-in terminals to support
on-site wiring. Six large fast sockets support 2.5-10 square power
lines, ａnd four small fast sockets support 2.5-4 square power lines.
DCDU-12B
supports 1 * BBU + 6 * RRU + 1 * FAN or 4BBU + 1 * FAN power supply.
More than three RRUs require 2 routes ａnd 16 inputs. See Appendix 1 for
details.
The following points should be paid attention to when two open parallel circuits supply the same DCDU-12B power:
- Two open channels must be output by the same power supply system.
- The specifications of the two openings must be exactly the same (including the size ａnd model of the openings).
-
The specifications of the two input power lines must be exactly the
same (including the length ａnd diameter of the power lines, etc.).
