NetSure 731 AA1-S2 Embedded Telecom DC Power System
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.
