华为DCDU-12B直流配电单元48V160A 输出10路 华为DCDU-12B
参数
指标
功能
实现一路-48V DC输入,10路-48V DC输出,给BBU、RRU等设备供电。
输入电流
1. 输入能力1*80A或2*80A。
2. 1*80A输入电源线线径为1路16mm^2电源线。
3. 2*80A输入电源线线径为2路16mm^2电源线。
配电规格
10*30A(6个大快插端子+4个小快插端子)
尺寸(宽*高*深)
442mm*42mm*65mm

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.
