All in one Design: Supports AC power input and integrated frame design.

IP65 Protection: IP65-rated enclosure offering complete dust protection and strong water resistance, ideal for harsh environments such as desert regions.

Intelligent Monitoring: Equipped with multiple sensors to monitor temperature, humidity, smoke concentration, and door status in real time, enabling early detection of fire, flooding, and equipment faults to ensure safety.

Multi-Layer Power Distribution: Integrated system supports DC, bidirectional battery, and AC power distribution. 1U circuit breakers come with full protection mechanisms including overload, short circuit, and undervoltage protection, plus surge protection. LLVD and BLVD circuits prevent battery over-discharge, extending battery life.

Hot-Swappable Module Design: 1U hot-swappable charging modules with intelligent current sharing and redundancy. In case of module failure, load is automatically redistributed to ensure continuous charging and power supply. Modules can be replaced without system shutdown, ensuring uninterrupted operation and easy maintenance.

High Efficiency Energy Saving: Rectifier modules deliver over 96% efficiency with a power factor of 0.99 and low harmonic distortion. Output adjusts dynamically with load demand, reducing energy consumption and operational costs.

Dual Cooling System: Built-in 1000W air conditioner ensures thermal management in high-temperature areas. In case of air conditioner failure, an emergency fan automatically activates for continued cooling.

Centralized Monitoring: Integrated FSU enables centralized monitoring of rectifiers, inverters, and lithium batteries. Real-time parameter tracking supports intelligent full lifecycle management. Based on B/S architecture, the system supports web access and offers an intuitive, user-friendly interface.

Standard Interfaces for Integration: Supports SNMP and Modbus protocols for seamless integration with upper-layer or third-party systems.
