About This Part
The Part Number ETP4850-D1A2, a Huawei ETP4850-D1A2, represents a sophisticated embedded DC power system within Huawei's renowned power product family. This compact, modular power solution is engineered to deliver stable and reliable -48V DC power, crucial for the continuous operation of sensitive telecommunications and data centre equipment. Its primary function is to convert incoming AC power (typically 220V or 380V AC) into a regulated -48V DC output, with a robust current capacity of up to 50A, as indicated by its model designation. The system typically comprises hot-swappable rectifier modules, such as the R4850G2, which boast high power conversion efficiency, alongside an advanced monitoring unit (e.g., SMU01A or SMU01B) for comprehensive system management, alarm reporting, and remote control capabilities. This design ensures high availability, energy efficiency, and ease of maintenance, making it a cornerstone for critical infrastructure power requirements. The Huawei ETP4850-D1A2 finds extensive deployment in a wide array of mission-critical environments where uninterrupted DC power is paramount. It is commonly installed in communication base stations (2G, 3G, 4G, and 5G), access network sites, microwave transmission stations, and various enterprise network deployments. Telecom operators, internet service providers (ISPs), and large enterprises across diverse industries rely on this system to power their core and edge network infrastructure, including wireless base transceiver stations (BTS), NodeBs, eNodeBs, BBU units, optical line terminals (OLTs), and digital subscriber line access multiplexers (DSLAMs). By providing a stable and protected power source, the ETP4850-D1A2 effectively mitigates risks associated with power fluctuations, outages, and grid instability, thereby ensuring service continuity and network reliability. Its modularity also facilitates straightforward upgrades and expansions, often replacing older, less efficient power solutions. For B2B clients seeking cost-effective and reliable infrastructure solutions, Revo Distribution Limited offers used and refurbished units of the Huawei ETP4850-D1A2.
