Product Overview
The Huawei R4815N1 is a high-power-density full digital rectifier module, professionally developed and fully compatible with Huawei ETP4830-A1 embedded communication power cabinet. It supports dual AC input modes of 100/120V and 200/240V, with an ultra-wide working voltage range of 85~300VAC. This module converts alternating current into adjustable -42~-58VDC standard telecom voltage, with a rated power of 1000W and rated current of 15A at the default 53.5VDC. Adopts advanced high-frequency switching and active PFC technology, achieving peak efficiency up to 94% and full-load power factor over 0.99, effectively reducing long-term operating power consumption. It comes with standard hot-swap design and built-in CAN bus communication interface, enabling online module replacement without system shutdown, as well as remote parameter adjustment, real-time monitoring and fault alarm via the cabinet monitoring unit. With compact structure, stable performance and comprehensive protection functions, it is widely used for new deployment, capacity expansion and spare replacement of indoor 4G/5G base stations, FTTx OLT and DSLAM cabinets.
