Product Overview
The Vertiv NetSure 531A32 is a fully integrated embedded DC power system launched by Vertiv (Former Emerson), specially optimized for LTE, 4G/5G macro base stations and FTTx communication scenarios. This compact subrack supports a maximum total power of 6KW and 200A output current, and can be equipped with up to 3 pieces of R48-2000e3 / R48-2000A3 high-efficiency rectifier modules. It features an ultra-wide AC input range of 85~300VAC (nominal 200~250VAC), which adapts to unstable municipal power and diesel generator power supply. With peak rectifier efficiency reaching 96.2% and overall system efficiency over 95%, plus built-in ECO sleep technology and mixed operation of high-efficiency and standard modules, it achieves excellent energy-saving effects. The system integrates AC distribution, battery distribution, multi-channel DC distribution and multi-stage lightning protection, and is equipped with M221S / M830B monitoring controllers. Rich communication ports support remote monitoring and parameter management. Small size and embedded design greatly reduce installation costs, widely used for new construction, renovation and capacity expansion of various indoor and outdoor telecom power cabinets.
Key Features
Ultra-wide Input Adaptation: AC input ranges from 85VAC to 300VAC (50/60Hz), compatible with global mains and generator power, stable under severe voltage fluctuation
High Energy Efficiency: Matched with R48-2000e3 rectifiers with 96.2% peak efficiency; system efficiency exceeds 95%. ECO sleep technology and mixed module operation further cut power consumption
