About This Part
The Huawei ETP48400 is a high-performance, rack-mountable DC power system engineered to deliver stable and reliable -48V DC power to critical telecommunications and data centre infrastructure. As a core component within Huawei's extensive power solutions portfolio, this system integrates advanced rectifier modules, a sophisticated monitoring unit, and comprehensive battery management capabilities. Designed for deployment in standard 19-inch racks, the ETP48400 typically accepts a wide range of AC inputs (e.g., 220V/380V three-phase) and efficiently converts it to a regulated -48V DC output, often supporting a maximum output current capacity of up to 400A, depending on the rectifier configuration. Key technical specifications include high power conversion efficiency, hot-swappable modules for ease of maintenance and scalability, and intelligent monitoring features accessible via standard communication interfaces like RS485, enabling remote management and fault diagnosis. This robust design ensures continuous operation and optimal performance for connected equipment. The Huawei ETP48400 finds extensive application across various critical network environments, serving as the backbone for power delivery in telecom base stations, central offices, mobile switching centers, and enterprise data centers. It is instrumental in supporting a wide array of network platforms and systems, including core network routers, access network equipment, transmission systems, and servers requiring a stable -48V DC supply. Leading mobile network operators, fixed-line providers, and internet service providers globally deploy the ETP48400 to ensure uninterrupted service delivery. This system effectively solves the critical problem of maintaining power during AC grid fluctuations or outages, providing essential backup power through integrated battery solutions. It serves as a vital upgrade path for older, less efficient power systems, enhancing overall network reliability, reducing operational expenditures through improved energy efficiency, and providing the necessary power redundancy for mission-critical operations.
