Vertiv(Emerson) NetSure 531A41 DC Power System with R48-2000e3 Rectifier

Specifications

Product Overview

The Vertiv NetSure 531A41 is a high-performance embedded DC power subrack developed by Vertiv (Former Emerson), specially designed for LTE, FTTx and all kinds of telecom equipment. This complete power system is fully matched with R48-2000e3 high efficiency rectifier modules, supporting up to 4 rectifier units with a total power range of 2kW to 8kW and maximum output current of 120A. It adopts 85~300VAC ultra-wide single-phase input, adapting to complex municipal power and diesel generator power environments. Equipped with advanced full digital control and active PFC technology, the rectifier peak efficiency reaches 96.2% and system efficiency exceeds 95%, effectively cutting long-term operating costs. This subrack features hot-swap rectifier design, comprehensive lightning protection, intelligent battery management and rich communication interfaces. Compact structure and embedded installation mode save cabinet space, which is widely used for new deployment, capacity expansion and old equipment replacement of indoor and outdoor telecom base stations, FTTx access cabinets and communication equipment rooms.
