6KW 200A DC Power System Embedded DC Power Subrack with 96.2% Rectifier Peak Efficiency for Telecom Base Stations

The Vertiv NetSure 531 A32 is a high-performance rack-mounted embedded DC power subrack developed by Vertiv (formerly E merso n). It is configured with R48-2000e3 high-efficiency rectifier modules and M221S/M830B monitoring controllers, supporting up to 3 × 2000W rectifiers for a total power of 6KW and a maximum output current of 200A.

The system features an ultra-wide AC input range of 85~300VAC (nominal 200~250VAC, 50/60Hz), adapting to unstable municipal grids and diesel generator power sources. The rectifier achieves a peak efficiency of 96.2%, and overall system efficiency exceeds 95%. It adopts ECO sleep technology and supports mixed operation of high-efficiency and standard modules for improved energy savings. 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 in new construction, renovation and capacity expansion of LTE, FTTx, macro base stations and various outdoor telecom cabinets.

• Wide Grid Compatibility: 85~300VAC ultra-wide input (50/60Hz) operates steadily under voltage fluctuation and generator power supply, suitable for diverse power environments.
• High Energy Saving: R48-2000e3 rectifier with 96.2% peak efficiency; system efficiency over 95%. ECO sleep technology further reduces idle power consumption.
• Flexible Capacity: Up to 3 × 2000W rectifier modules, total power up to 6KW and 200A output, flexible to match different load demands.
• Excellent Temperature Resistance: Operating temperature ranges from -40℃ to +80℃, with full-power output within -40℃ ~ +65℃, reliable for high and low temperature outdoor scenarios.
• Multi-level Lightning Protection: Professional protection design for AC, DC and signal sides, effectively resisting lightning surges in complex outdoor environments.
• Intelligent Battery Management: Real-time monitoring, temperature compensation and over-discharge protection extend battery service life.
• Rich Communication Ports: Built-in RS232, Ethernet and dry contact interfaces, supporting remote monitoring, parameter configuration and fault alarms.
• Compact Structure: Standard rack-mounted design, small size and light weight (13kg without modules), greatly reducing installation and deployment costs.
• Walk-in Startup Function: Avoids impact on front-end equipment during startup, improving overall system stability.
