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.).
