Product Overview
The Vertiv R48-3000 and R48-3000E3 belong to the classic eSure series rectifiers developed by former Emerson (now Vertiv). This 3000W high-performance digital rectifier is widely matched with Vertiv NetSure embedded telecom power systems. It features a wide AC input range of 85~300VAC, and converts alternating current into adjustable 42~58VDC standard telecom voltage (default 53.5VDC) with a maximum output of 62.5A/3000W. Adopts advanced DSP digital control and patented switching technology, achieving peak efficiency of 96.5% and full-load power factor over 0.99, which effectively reduces operational power consumption. Equipped with standard hot-swap structure, the module supports online replacement without shutting down the entire cabinet. It also realizes intelligent parallel operation and remote monitoring via built-in communication interface. Compact size suits short-depth racks, making it an ideal choice for new deployment, capacity expansion and spare replacement of FTTx OLT, DSLAM and 4G/5G base station power cabinets.
