About This Part
The Part Number ETP48120 designates a highly efficient, embedded DC power system manufactured by Huawei, engineered to deliver stable and reliable -48V DC power for critical telecommunications and data center infrastructure. This compact power solution, part of Huawei's extensive embedded power product family, typically features a rack-mountable form factor, optimizing space utilization within equipment cabinets. Its primary function is to convert AC input power into a regulated -48V DC output, supporting a maximum current output of 120A, thereby providing a robust power capacity suitable for various network elements. Key technical specifications include a wide AC input voltage range, high power conversion efficiency (often exceeding 96%), and advanced features such as hot-swappable rectifier modules, intelligent battery management capabilities, and comprehensive monitoring and alarm functions accessible via standard communication protocols like SNMP. This system ensures continuous operation and protects sensitive equipment from power fluctuations. The Huawei ETP48120 power system is extensively deployed across a multitude of critical infrastructure environments, including cellular base stations (BTS), mobile switching centers (MSC), data centers, and enterprise communication rooms. It serves as the backbone for powering essential network elements such as BBU (Baseband Units), RRU (Remote Radio Units), transmission equipment, and various active network devices requiring a stable -48V DC supply. Telecommunication operators globally, internet service providers, and large enterprises leverage this system to ensure uninterrupted service delivery for their 2G, 3G, 4G, and emerging 5G networks. This robust power solution addresses the critical need for reliable power in remote and urban sites, mitigating risks associated with grid instability and ensuring continuous operation through integrated battery backup management. It often replaces aging, less efficient power infrastructure, providing a modern, scalable, and energy-efficient upgrade path for network expansion and modernization initiatives.
