Intelligent DCDU for Base Stations

Under the guidance of national macro policies, domestic telecom operators have been actively expanding base station infrastructure. Meanwhile, as the collaborative construction and sharing initiative continues to advance, the number of operators co-locating their equipment at the same base station is steadily increasing. To standardize DC power management for operator base stations and ensure differentiated support for equipment from various providers, an intelligent DCDU solution tailored for all scenarios has been introduced.

Product Introduction
The Intelligent Distribution Unit (DCDU) serves as the battery connection port and DC output distribution point for base station switching power supplies. It offers two optional structural designs: a modular, independently pluggable switch for each circuit, or a multi-circuit, integrated design—and can be cascaded as needed. The unit supports advanced features such as differentiated backup power/generation management, precise tenant-based energy management, DC circuit/tenant (group) metering, hard-off energy-saving control for individual circuits (or residential units), and customizable blackout period management. Additionally, it allows users to define custom capacities for circuit switches and tailor circuit and group configurations to their specific needs.

Industrial Efficiency

  • It can provide differentiated backup power duration guarantees for different tenants and distinct DC circuits.
  • It standardizes the DC power management for operators' base stations, ensuring that all output branches feature precise load-sharing control to prevent operators from illegally reconnecting their own load branches.
  • All DC equipment within the base station is individually metered for power consumption, with customizable rules for aggregating energy data, and tenant-specific electricity bills are generated accordingly.
  • Implement energy-saving hard shutdowns of 5G base station AAUs by cell during late-night hours, or, based on real-time traffic data analysis from the OMC, enforce hard-shutdown energy savings for either the coverage layer or the capacity layer in multi-network areas where 4G and 5G coexist.
