华为DCDU-12B直流-48v分配单元 华为DCDU-12B

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.).
