Scenario application value of embedded communication power supply

With the increase of edge nodes in communication networks and the popularization of miniaturized devices, it is difficult 

for traditional rack-mounted centralized power supply to adapt to the deployment scene with limited space. Embedded 

communication power supply has become the mainstream power supply scheme for small sites and embedded devices 

because of its small size and high integration, which greatly reduces the deployment difficulty and space cost while ens-

uring the reliability of power supply.

Core technical characteristics

The embedded power supply adopts a highly integrated design, which integrates the rectification, control and protection 

circuits in a small shell, and can be directly embedded in the equipment cabinet, integrated cabinet or small cabin without 

occupying additional independent installation space. The mainstream embedded power module adopts high-frequency 

switching topology, which has high conversion efficiency and low heat generation, supports wide voltage input, can adapt 

to complex power grid environment, and comes standard with full protection of overvoltage, undervoltage, short circuit 

and overtemperature to ensure the safety of itself and back-end loads. Compared with the discrete power supply scheme, 

the embedded model has simpler wiring and more perfect internal electromagnetic compatibility design, which can effect-

ively avoid signal interference to peripheral communication boards and is suitable for matching precision equipment with 

high power supply stability and electromagnetic environment requirements.

Mainstream application scenarios

Small communication base stations and remote nodes: 5G edge stations, remote units and other scene spaces are limited. 

Embedded DC power supply can be directly integrated into the equipment cabinet, and a complete backup power supply 

system can be formed by supporting storage batteries, so there is no need to configure a separate power cabinet, which 

greatly reduces the site construction cost. Integrated communication cabinet: The outdoor integrated cabinet integrates 

power distribution, transmission and battery, and the embedded communication power module can be directly clamped 

inside the cabinet to uniformly supply power to all equipment in the cabinet, with compact structure and high protection 

level, which is suitable for outdoor complex environment. Industrial embedded equipment: industrial computer, monitoring 

terminal, security equipment and other embedded equipment can be built with embedded power supply of corresponding 

specifications, which can directly convert the commercial power into the DC voltage required by the equipment, without 

external independent power adapter, thus improving the overall integration and reliability of the equipment.

Key points of type selection

The selection must first match the output voltage and power. The mainstream of the communication scene is 48V output, 

so a reasonable margin should be reserved according to the total power of the back-end equipment to avoid long-term 

full-load operation. Secondly, we should pay attention to the installation size and pin definition to ensure accurate adapt-

ation to the installation position of the target equipment. In special circumstances, it is necessary to confirm the protection 

level and temperature tolerance range, and outdoor scenes need to use moisture-proof and dust-proof reinforced models. 

In the scene of intelligent management requirements, the communication power module with communication interface is 

preferred, which can be connected to the upper system to realize remote parameter monitoring and status alarm, so as to 

adapt to the operation and maintenance requirements of unattended stations.
