What this product is

What this product is

Architecturally, the M500F employs a dual-bus distributed supervision model. The central controller board hosts a deterministic real-time operating system that monitors rectify clusters, distribution panels, and auxiliary environmental sensors via galvanically isolated CAN and RS485 physical layers. Upstream network convergence is achieved via an integrated 10/100Base-T Ethernet port supporting SNMPv1/v2c/v3, HTTPS WebUI, and Modbus-RTU. The module meets IEC/EN 60950-1 safety requirements and complies with stringent telecom EMC immunity standards, featuring live hot-swappable mechanical insertion.

What problem it solves

The M500F mitigates operational risks including catastrophic battery thermal runaway, unrecoverable deep-discharge degradation, high operational expenditure caused by non-optimized rectifier low-load efficiencies, and delayed environmental alarm propagation (flood, smoke, temperature anomalies) in unstaffed remote installations.

Who and where it is for

Ideal for 4G/5G macro cell towers, Centralized Radio Access Network (C-RAN) hub sites, optical long-haul transport repeaters, rail signaling power panels, and large-scale enterprise DC power plants (such as the Emerson/Vertiv NetSure series).

Core advantages

  • Dual-bus distributed architecture with hardware watchdog ensures high reliability and zero single-point-of-failure.
  • Supports SNMP, HTTPS, and Modbus-RTU protocols for seamless integration with OSS/DCIM management systems.
  • Precise battery charge/discharge and rectifier efficiency control eliminate thermal runaway and deep discharge risks.
  • Engineered for -20°C to +70°C operation and industrial surge standards with live hot-swappable capability.
