Integrated DC Power Supply

Product Overview

The Huijue Network Integrated DC Power Supply is an outdoor power system specifically built for 5G small cells, micro base stations, street level telecom sites, pole mounted stations, and remote communication facilities.

This integrated power supply system integrates the functions of rectification, DC distribution, monitoring, surge protection, and battery back-up in a modular power supply system. The outdoor power system module can operate in collaboration with either one or more lithium battery module, delivering reliable DC power with the option to scale up its back-up power capacity.

Whereas the traditional telecom power systems require a separate equipment room or big cabinet for operation, this compact system can be installed directly on the communication site. It is wall mountable, pole mountable, tower mountable, and ground mountable.

Modular Power Architecture

It is mainly made up of an outdoor power unit and outdoor battery units, which differ from the conventional large power cabinet.

The power unit includes the functionalities that are essential for DC power management in the telecom industry, including the following functionalities:

• AC/DC rectification
• DC power distribution
• Monitoring
• Surge protection
• Battery charging
• Communications

The battery module is made up of modular Li-ion batteries with BMS embedded within. Several battery units can be interconnected depending on the desired backup time and telecom loads.

This design helps in configuring the power system according to the site requirements.

Compact Design for Small Telecom Sites

A 5G small cell network can be set up in places that have very little space for the installation of equipment, like street poles, buildings, lamp posts, and small outdoor platforms.

Because of the small size of the integrated DC power system, it is possible to install the power system close to the communication system without having a power room dedicated to it.

Suitable for:

• 5G small cells
• Micro base stations
• Street-level base stations
• Telecom pole systems
• Communication lamp post systems
• Repeaters
• Wireless communication systems

Flexible Battery Backup

The system may be fitted with one or several LiFePO₄ battery modules, based on the backup period needed.

In the course of its regular operation, the power module powers the telecom load as well as the battery modules. In case of an interruption in the AC input, the battery modules automatically provide backup DC power for the communication equipment.

Several battery modules may be added in case of a longer backup period needed.

Outdoor Power Module

The outdoor power module is intended for outdoor deployment directly into telecom applications.

All the rectifying, distributing, monitoring and protective features have been incorporated into a single device which will eliminate the need for multiple power devices.

This module may have a fanless thermal management system with an external dissipating mechanism that will help in eliminating mechanical parts.

Depending on the harshness of the environment, the casing and all other elements can be made based on their respective requirements.

Intelligent Battery Management

Each module of the battery pack contains a Battery Management System (BMS), which monitors essential parameters of the battery and controls charging and discharging.

Parameters monitored by the BMS are:

• Battery voltage
• Charging & discharging current
• Battery temperature
• State of Charge (SOC)
• Battery protection status
• Battery alarms
• Battery operation parameters

The battery packs have an interface with the power system for coordinated charging, protection, and monitoring.

Easy Installation

Another advantage of the integration system is the flexibility in installation.

According to the arrangement of the premises, the system can be installed as:

• Wall-mounted installation
• Pole-mounted installation
• Installation on a telecom tower
• Installation on a lamp post
• Ground installation
• Equipment platform installation outside

The small and light modular design makes the transportation and on-site installation of the system more convenient than conventional telecom power systems.

Intelligent Monitoring

The integrated monitoring feature enables you to see how the power module and battery modules are functioning.

Based on the settings, this technology may support 4G wireless communication, Bluetooth local monitoring, and other communication interfaces, enabling you to monitor the status of your system remotely or using a nearby mobile phone.

Typically, the monitoring data include:

• AC input status
• DC output voltage
• Output current
• Rectifier status
• Battery SOC
• Battery voltage
• Battery temperature
• System alarms
• Communication status

Technical Specifications

Specifications can be customized according to telecom load, backup requirements, installation method, and project conditions.

Application

5G Small Cells

It offers compact DC power and battery backup capabilities for 5G small cell installations where installation space is limited.

Micro Base Station

It integrates power conversion, power distribution, power monitoring, and power backup capability into one module outdoor system for micro base stations.

Communication Sites on Poles

The compact system design allows the installation of the system on communication poles and other vertical infrastructures without the need for an extensive equipment cabinet.

Street-Level Telecom Sites

Designed for use in city-wide 5G deployments where telecom equipment must be installed on street furniture, buildings or other location-limited places.

Remote Communication Sites

It may be used as the DC power platform for remote communication systems and may be integrated with solar or other renewable power sources as needed.
