Product Overview
The Vertiv NetSure 531 A32 is a high-performance rack-mounted embedded DC power subrack developed by Vertiv (Former Emerson). It is configured with R48-2000e3 high-efficiency rectifier modules and M221S/M830B monitoring controllers, supporting up to 3 pieces of 2000W rectifiers with a total power of 6KW and maximum output current of 200A. This system features an ultra-wide AC input range of 85~300VAC (nominal 200~250VAC, 50/60Hz), which adapts to unstable municipal grids and diesel generator power sources维谛技术(Vertiv). The rectifier achieves a peak efficiency of 96.2% and the overall system efficiency exceeds 95%. It adopts ECO sleep technology and supports mixed operation of high-efficiency and standard modules for better energy-saving performance. Integrated with multi-level lightning protection, intelligent battery management and complete communication interfaces, this compact subrack saves installation costs and space. It is widely used for new construction, renovation and capacity expansion of LTE, FTTx, macro base stations and various outdoor telecom cabinets.
