Why does the communication room prefer modular rectifier power supply?

In communication base stations, data centers and other scenes that require high reliability of DC power supply, rectifier power supply is the core of 

distribution system. The traditional integrated rectifier power supply has a fixed structure, and the failure of a single component easily leads to the 

shutdown of the whole machine, high maintenance cost and high power supply risk. However, the modular rectifier switching power supply has 

become the mainstream scheme in the industry with its building block architecture.

Modular rectifier switching power supply is composed of several independent power modules with complete rectifier function, and the system 

capacity can be flexibly adjusted by adding or subtracting modules. When expanding business, it is not necessary to replace the whole machine, 

and the upgrade can be completed by adding new modules. Single module failure supports hot plug replacement, which does not affect the normal 

power supply of other modules in the whole process, and fundamentally solves the pain points of traditional power supply, such as difficult expansion, 

complicated maintenance and low reliability.

Modular design brings multi-dimensional performance improvement. Under the N+1 redundant configuration, a single module can still bear all loads 

when it fails, ensuring uninterrupted power supply. On-line hot plug feature greatly shortens the fault handling time and reduces the risk of operation 

and maintenance downtime; At the same time, the high-frequency switching technology is adopted, and the efficiency of the whole machine can reach 

more than 90%, effectively reducing the operating energy consumption. Baoweite modular rectifier system has optimized circuit topology, high efficiency 

and high power factor ≥0.99, and adopts standard 19-inch rack design, which can perfectly meet the deployment requirements of various computer 

rooms and base stations.

At present, this kind of power supply has been widely used in telecom base stations, data centers, rail transit and other fields, providing stable and pure 

DC power supply for core facilities such as servers, switches and signal equipment.

When selecting the model, it is suggested to reserve 20%-30% capacity allowance in combination with the load growth in the next 3-5 years, so as to 

ensure that the parameters of the same system module are consistent to achieve good current sharing, and at the same time, select products with 

corresponding protection levels according to the temperature, humidity and dust conditions at the installation site. In daily operation and maintenance, 

it is necessary to regularly check the fan operation, clean up the dust accumulated in the inlet air, monitor the voltage and current balance of each module, 

and extend the service life of the equipment through normal maintenance.

Generally speaking, modular rectifier power supply has become the development trend in the field of DC power supply with its advantages of high reliability, 

easy expansion and easy maintenance. Baoweite's full range of modular rectifier power supplies cover a variety of power specifications, support hot plug, 

intelligent monitoring and multiple protection mechanisms, and can be widely adapted to various DC power supply scenarios.
