Product Overview
The Vertiv R48-12000E & R48-12000LE belong to flagship eSure high-power series three-phase rectifiers originally developed by former Emerson Vertiv, specially customized for NetSure large-capacity core telecom power cabinets and medium-sized data center DC power systems. Two variants with different AC input specs: R48-12000E for three-phase 340~528V industrial grid; R48-12000LE for single/three-phase 176~264V commercial grid, both rated max 11600W@48VDC adjustable output(48~58VDC). Adopts advanced DSP full digital control + high-frequency soft-switch topology, peak conversion efficiency up to 96.3%, full-load PF≥0.99, excellent energy-saving performance. Features standard hot-swap drawer design, backward compatible with legacy Vertiv rectifier part numbers:486534000/486534001/486532600/486532601/486532602; built-in intelligent parallel control and CAN communication, multi-module automatic load sharing without extra accessories, widely applied in provincial core telecom equipment room, medium data center, large outdoor centralized base station power renovation projects.
