The integrated cabinet series converts 380V/220V AC power into stable 48V DC power via high-frequency rectifier modules.It provides standardized installation space for embedded plug-in frames, battery banks, monitoring modules, and communication equipment, enabling orderly equipment deployment.
The THJK102G series integrated monitoring unit (link) collects system data in real time to enable battery management, load control, fault alarms, and remote communication.
Environmental Protection: Provides IP20/IP30 protection (depending on indoor or outdoor models)
- Space Optimization: The embedded plug-in frame is installed directly inside the cabinet and deployed alongside communication equipment, significantly saving server room space and simplifying cabling complexity.
- Easy Maintenance: The cabinet design fully accommodates O&M requirements. Power modules support hot-swapping, allowing maintenance personnel to replace faulty modules without powering down the system. The cabinet doors open wide, and the internal cable management channels are clearly organized, making daily inspections and troubleshooting easy and efficient.
- Intelligent O&M: The monitoring unit of the embedded rack-mount chassis connects to the external network via cabling within the cabinet, enabling remote monitoring and management and reducing O&M costs.
