,85-300V Ultra-Wide AC Input Range Telecom DC Power Cabinet
,96% Peak Efficiency Embedded Telecom DC Power System
High-capacity subrack-type DC power solution for multi-tenant telecom base stations and central machine rooms.
The NetSure 731 AA1-S2 is a high-capacity subrack-type embedded DC power system developed by Vertiv (formerly Emerso n), tailored for large-scale multi-tenant telecom base stations and central machine rooms. It adopts 3-phase 5-wire AC input and features an ultra-wide voltage range of 85–300V (output derating below 176V). Equipped with R48-3000 series rectifier modules and an M5306 controller, the system delivers a maximum DC output current of 600A. Its normal efficiency reaches 95% and peak efficiency hits 96%, combining energy-saving performance with stable output.
This integrated unit combines AC/DC distribution, multi-level lightning protection, intelligent battery management, and multi-user power distribution functions. With a modular hot-swap design, front maintenance layout, and strong environmental adaptability, it supports independent power metering for up to 4 tenants. It is a reliable core power solution for large communication networks, data center supporting power, and shared base station projects.
- Ultra-Wide Grid Adaptation: 85–300V AC wide input range, compatible with mains and generator power; output derating is automatically triggered when voltage is lower than 176V to ensure system safety.
- High Power Capacity: Maximum 600A DC output, suitable for large equipment clusters and multi-tenant shared communication sites.
- Superior Energy Efficiency: Normal efficiency ≥95%, peak efficiency up to 96%; supports module sleep and ECO energy-saving mode to reduce idle power consumption.
- Professional Module Configuration: Matches R48-3000 rectifier modules and M5306 controller, with standard 125A AC/DC circuit breakers for reliable power distribution.
- Multi-Tenant Management: Supports up to 4 independent users, equipped with separate power distribution circuits and power metering functions for refined management.
- Comprehensive Lightning Protection: AC SPD (Class C) and DC 10kA surge protection, effectively resisting outdoor lightning and transient surges.
- Intelligent Battery Management: Built-in BLVD protection, temperature compensation, automatic charge switching, and online battery testing to extend battery service life.
- Modular Hot-Swap: Rectifier and controller modules support hot plugging. Maintenance and replacement can be done without system shutdown.
- Walk-In Soft Start: Avoids current impact on front-end transformers and generators during startup, protecting the entire power grid.
- Rich Interfaces: Equipped with RS232, Ethernet, and dry contact ports to realize remote monitoring, parameter configuration, and fault alarm.
- Large 4G/5G multi-tenant shared macro base stations
- Telecom central machine rooms and backbone transmission equipment rooms
- Large-scale FTTX broadband access power distribution systems
- Data center DC power supply and battery backup projects
- Industrial communication equipment and high-load network frame systems
