The HJDUM01 Series Wall - mounted Communication Switching Power Supply System: A Reliable Energy Guarantee for Communication Equipment

Ⅰ. Product Overview

The HJDUM01 series wall – mounted communication switching power supply system is carefully developed specifically for the actual usage scenarios of communication equipment and energy – saving and emission – reduction requirements. It includes both indoor and outdoor – type wall – mounted high – frequency switching power supply systems, which can well adapt to different application environments. Whether in an indoor communication equipment room or an outdoor base station, it can provide stable power support.

Ⅱ. Outstanding Performance Features

(Ⅰ) Wide – voltage Input and High – efficiency Conversion

1. Wide – voltage Adaptability

    – The HJDUM01 series shows great compatibility in terms of voltage input. Its modules allow the grid input voltage to vary between 90Vac and 300Vac. This means that whether in remote areas with unstable grid voltages or urban areas where voltage fluctuations may occur during peak electricity consumption, this power supply system can stably connect to the grid and operate normally, ensuring the continuity of power supply for communication equipment.

2. High – efficiency Conversion Technology

    – This series adopts advanced topological circuits and realizes soft – switching technology within a wide load range, with a conversion efficiency of 96% or higher. This highly efficient electrical energy conversion mechanism reduces energy waste and operating costs. For communication operation enterprises, significant energy cost savings can be achieved in the long – term operation.

(Ⅱ) Intelligent Monitoring and Battery Management

1. Intelligent Battery Charging Management

    – Its intelligent monitoring unit adopts an advanced charging management mode for storage batteries. This management mode can automatically adjust the charging strategy according to the battery’s status, such as the charge level and temperature, avoiding over – charging or under – charging situations, thereby effectively extending the battery’s service life. In communication networks, reliable backup batteries are crucial for dealing with sudden power – outages, and extending the battery life means improving the emergency support capabilities of the communication system.

2. Remote and Local Monitoring

    – The system supports local or remote centralized monitoring through RS – 485 or TCP/IP network card interfaces. Maintenance personnel can view the real – time operating parameters of the power supply system, such as voltage, current, and power, on the local operation interface. They can also monitor and manage the power supply systems distributed in various locations through remote network connections at the control center. This monitoring method greatly facilitates the maintenance and management of the power supply system, especially when dealing with power supply issues at multiple scattered sites, enabling quick response and fault resolution.

(Ⅲ) Reliable System Protection and Metering Functions

1. Comprehensive Protection Mechanism

   The HJDUM01 series has a variety of protection and alarm functions, including over – current, over – voltage, and over – temperature protection. In the face of sudden abnormal situations in the power system, these protection mechanisms can start quickly to ensure the safety of the power supply system itself and the connected communication equipment. For example, when lightning strikes or surges occur, its multi – stage surge protectors can withstand current surges of 8/20 μs waveform 20kA (maximum 40kA), preventing the powerful current from damaging the system.

2. Accurate Metering Function

     This power supply system has a DC total electricity metering function, which can accurately measure the electricity usage. This is of great significance for communication operation enterprises to calculate energy costs, analyze energy – use efficiency, and formulate energy – saving strategies. Through the analysis of electricity – use data, enterprises can optimize equipment configuration and operation modes to further improve energy utilization.

(Ⅳ) Convenient Operation and Environmental Adaptability

1. Module Hot – swapping and Front – side Operation

    – The rectifier modules in the system support hot – swapping, and all adjustments and operations can be completed on the front side. This design greatly improves the convenience of maintenance. When a module fails and needs to be replaced, maintenance personnel do not need to shut down the entire power supply system. They can directly replace the module by hot – swapping on the front side, greatly shortening the equipment downtime and ensuring the uninterrupted operation of communication services.

2. Wide – temperature Environment Adaptability

    The HJDUM01 series can operate normally within a wide temperature range of – 40℃ to 75℃. Whether in cold polar regions, hot desert areas, or outdoor environments with large temperature variations, this power supply system can stably and reliably operate, providing stable power guarantee for communication equipment.

Ⅲ. Wide – range Application Scenarios

Due to its excellent performance and adaptability, the HJDUM01 series wall – mounted communication switching power supply system is applicable to various indoor and outdoor scenarios such as mobile communication base stations, integrated access network nodes, and distributed base stations. With the booming development of mobile communication today, whether it is a dense base station network in the city or a signal – covering base station in remote areas, this power supply system can meet the strict requirements for power supply, ensuring the stable transmission of communication signals.

The HJDUM01 series wall – mounted communication switching power supply system, with its advanced technology, reliable performance, and wide – range adaptability, has become an ideal choice in the field of communication power supplies, providing a solid energy guarantee for the stable operation of modern communication networks.
