Integrated communication power supply cabinet: building an efficient and reliable 48V communication power supply system

With the development of communication network in the direction of wide coverage and deep extension, the power supply demand of various 

base stations, marginal computer rooms and transmission nodes continues to grow, and the problems of long deployment period, difficult 

operation and maintenance and insufficient system stability of traditional distributed power supply configuration are gradually highlighted. 

The integrated communication power supply cabinet highly integrates functional units such as rectification, power distribution, energy storage 

and monitoring, and becomes the core deployment scheme of 48V communication power supply system in a standardized and integrated form.

Integrated design, greatly reducing the deployment cycle.

The traditional communication power supply system needs to purchase rectifier module, power distribution cabinet, battery rack and monitoring 

equipment separately, and then assemble and wire them on site, which has many construction links and long period, and it is difficult to control 

the construction quality on site. The integrated communication power cabinet adopts factory prefabrication mode, which integrates the 48V 

communication power rectifier module, AC/DC power distribution unit, battery compartment, lightning protection device and intelligent monit-

oring unit into the standard cabinet, and completes the whole system debugging before leaving the factory. The site can be put into operation 

quickly only by connecting the mains input and load output lines, which greatly reduces the site construction amount and debugging period, 

especially for scenes that require high deployment timeliness such as batch base station construction and emergency site opening. The interior 

of the cabinet adopts the layout of strong and weak electricity separation, and the wiring is standardized and orderly, which not only reduces 

electromagnetic interference, but also facilitates the later operation and maintenance investigation.

Redundant architecture ensures continuous and reliable power supply.

The continuity of power supply is the core index of communication system, and the integrated cabinet constructs the full link redundancy guar-

antee system from input to output. The rectifier module adopts N+1 redundant configuration, and when a single module fails, the other modules 

automatically share the load, and the power supply is not interrupted during the whole process, and hot plug replacement is supported, and the 

operation and maintenance need not be stopped. STS static switch can be integrated in the front end, which supports millisecond seamless 

switching of two-way mains input and avoids the risk of single-way mains interruption. The cabinet is equipped with the installation position of 

battery pack as standard, and the battery power supply will be automatically switched when the mains supply is interrupted to ensure the conti-

nuous operation of key loads. At the same time, the whole machine has multiple protection mechanisms of overvoltage, undervoltage, overcur-

rent, short circuit, overtemperature and lightning protection, which can effectively resist power grid fluctuation and environmental interference 

and adapt to industrial-grade operating conditions.

Intelligent management to reduce the operation and maintenance cost of the whole link.

The traditional distributed power supply system relies on manual on-site inspection, which leads to the lag of fault detection and low efficiency 

of investigation, especially the high operation and maintenance cost of remote stations. The intelligent monitoring system is built in the integrated 

communication power cabinet, which can collect the operating parameters such as voltage, current, temperature and battery capacity of the whole 

system in real time, and automatically trigger photoacoustic and remote alarm in abnormal state. It supports standard communication interfaces 

such as RS485 and SNMP, and can be directly connected to the dynamic ring monitoring platform to realize remote parameter reading, state 

monitoring and control operation, greatly reducing the frequency of on-site inspection and adapting to the operation and maintenance requirem-

ents of unattended stations. Aiming at the battery pack, the system has built-in intelligent charging management function, which can automatically 

switch between floating charging mode and even charging mode, and cooperate with the temperature compensation mechanism, which can 

effectively prolong the cycle life of the battery and reduce the cost of consumables for long-term operation and maintenance.

Scenario adaptation, covering multiple deployment requirements.

Different deployment scenarios have significant differences in the capacity, protection level and installation form of the power cabinet, and the 

integrated cabinet can flexibly adapt to multiple scenarios. The indoor computer room adopts the standard 19-inch rack structure, which covers the 

full power section from the small edge site to the core computer room and is suitable for centralized deployment. The outdoor cabinet adopts a high-

protection shell, which is dustproof, waterproof and temperature-controlled, and is suitable for the environment without computer room such as field 

base stations and roadside optical stations. The small integrated model is compact, can be directly mounted or installed on the floor, and is suitable 

for space-limited scenes such as 5G micro base stations and indoor distribution systems. At the same time, the number of rectifier modules, battery 

capacity and functional interfaces can be flexibly configured according to actual needs, and the power supply requirements of different stations can 

be customized.

Generally speaking, the integrated communication power supply cabinet is a cost-effective scheme for upgrading the current communication power 

supply system by improving efficiency through integration, ensuring reliability through redundancy and reducing cost through intelligence. Baoweite's 

full range of communication power supply cabinets covers indoor and outdoor scenes, comes standard with high-frequency high-efficiency rectification 

system and intelligent monitoring unit, supports customized configuration on demand, and can stably support the high-reliability power supply requir-

ements of various communication network nodes.
