U300-G Series: Specialized DC Intelligent Dimming & Distribution Cabinet for Rail Transit
The U300 Series distribution cabinet is a high-performance solution designed for rail transit lighting. It features AC 3-Phase 380V input and DC 220V rated output, integrating advanced Manchester-coded DC Power Line Carrier (PLC) dimming technology. Developed in accordance with GB/T 3797-2016 and GB/T 7251.8-2020 standards, this system is purpose-built for rail infrastructure, including subway stations, urban rail hubs, and maintenance depots. It supports independent circuit dimming, zone-based control, and sensor-integrated smart dimming functionalities.
Product Features
High Efficiency & Energy Saving|
Centralized Conversion: Integrating dispersed driver units into the distribution cabinet increases overall system efficiency by 10%. |
|
High-Efficiency Conversion: Utilizes soft-switching LLC rectifier modules to achieve a peak AC/DC conversion efficiency of ≥94%. |
|
Smart Lighting Control: Features intelligent control logic to enable "lighting-on-demand," reducing energy consumption by up to 50%. |
01
Safety & Protection|
Floating DC Output: The electromagnetic isolation units within the rectifier modules ensure a floating ground DC output. This design eliminates the risk of electric shock from single-pole contact and prevents leakage during single-pole grounding. |
|
Extra-Low Voltage (ELV): Operates on a safe DC 48V output, strictly adhering to safety standards for lighting power supplies. |
02
Intelligent Monitoring|
Distribution Management: Comprehensive statistics on power usage, status monitoring of rectifier modules, and internal fault diagnostics. |
|
Lighting Control: Integrated monitoring for each lighting branch allows for precise control and customizable scheduling based on real-time requirements. |
03
Exceptional Reliability|
Environmental Adaptation: Fully sealed design with superior dust and salt-mist resistance, ideal for harsh environments. |
|
Hot-Swappable Maintenance: Both rectifier and branch control modules support hot-swapping. A single module failure will not interrupt the overall power supply or affect the operation of other circuits, ensuring zero downtime during maintenance. |
