Product Overview
The Vertiv NetSure 2100 A31 is a high-density 1U rack-mounted embedded DC power system, available in three configurations: S1 (40A), S2 (60A) and S3 (60A). It is fully assembled with M225S or M831A monitoring controllers and compatible R48-1000e3 rectifier modules, supporting up to 3 pieces of 1000W rectifiers with a total power up to 3kW. The system adopts 85~300VAC ultra-wide AC input and provides adjustable -42.3~57.6VDC standard telecom output, with rectifier peak efficiency reaching 95.4%. Designed with front-access circuit breakers and integrated distribution ports, it realizes convenient operation and maintenance. It is equipped with an intelligent battery management system, large-capacity alarm storage (up to 4000 records) and multiple communication ports for remote monitoring. With compact 1U size, low noise and reliable performance, it is widely applied in distributed antenna systems (DAS), 3G/4G/5G radio access nodes, FTTx wireline access networks and other telecom scenarios.
Key Features
Wide Voltage Adaptation: 85~300VAC input range (45~65Hz), compatible with global commercial grids and diesel generators, stable against voltage fluctuations
High Power Density: Standard 1U rack size (482×240×43.6mm), maximum 3kW total power, saves valuable cabinet space for high-density deployment
Excellent Efficiency: R48-1000e3 rectifier achieves 95.4% peak efficiency, effectively reducing long-term power consumption and operating costs
Front Access Design: All circuit breakers and connection terminals are arranged on the front panel, making daily inspection, wiring and maintenance more efficientVertiv
Integrated Distribution: Built-in AC distribution, battery distribution and multi-channel DC distribution circuits, no need for extra distribution accessories
Intelligent Battery Management: Supports battery low-voltage disconnection (BLVD) protection to prevent over-discharge and extend battery service life
Powerful Alarm Storage: Built-in memory stores up to 4000 alarm records, facilitating on-site fault query and troubleshooting
Diverse Communication Options: S1/S2 equipped with RS232 port, S3 equipped with RS485 and network ports, supports remote monitoring and parameter configuration
Low Noise Operation: Optimized cooling structure, low audible noise under normal load, suitable for indoor and semi-enclosed environments
Reliable Protection: Optional C-level lightning protection (≥10kA), compliant with EMC Class B standards for strong anti-interference capability
