19-inch 2U Marine Integrated DC Power System Embedded Power System for Telecom

The Vertiv NetSure 531A32 is a fully integrated embedded DC power system launched by Vertiv (formerly E merso n), 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), adapting to unstable municipal power and diesel generator supply. With peak rectifier efficiency reaching 96.2% and overall system efficiency above 95%, plus built-in ECO sleep technology and mixed operation of high-efficiency and standard modules, it achieves excellent energy-saving results.

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. Its small size and embedded design greatly reduce installation costs, making it widely suitable for new construction, renovation and capacity expansion of various indoor and outdoor telecom power cabinets.

• 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.
• Flexible Capacity Configuration: Max 3 × 2000W rectifier modules, total power up to 6KW, maximum output current 200A, flexible to match different load requirements.
• Comprehensive Distribution Design: Standard AC distribution (1×40A/2P), battery distribution (2×50A/1P) and 6-way DC distribution, with a reasonable circuit layout for multi-load power supply.
• Multi-level Lightning Protection: C-level 20kA protection on the AC side and D-level 10kA protection on the DC side, effectively resisting lightning surges in outdoor and complex environments.
• Wide Temperature Resistance: Rectifier operating temperature −40℃ to +80℃, full-power output within −40℃ to +65℃, reliable operation in high and low temperature areas.
• Intelligent Battery Management: Professional battery monitoring, temperature compensation and over-discharge protection, effectively extending battery service life.
• Diversified Communication & Alarm: Equipped with RS232, Ethernet and dry contact interfaces; supports multiple alarm output modes, convenient for remote networking and fault warning.
• Compact Embedded Structure: 19-inch standard rack size, light weight and small footprint, lowering installation and maintenance costs.
