U300-G Series (Standard Edition) – Intelligent DC Lighting Dimming & Distribution Cabinet

Product Features
Centralized Conversion: Dispersed drivers consolidated into the cabinet boost system efficiency 10%.
Advanced Conversion: 3rd-gen SiC rectifiers deliver ≥96% peak efficiency.
Demand-Based Control: Smart dimming cuts lighting energy use up to 50%.
Floating DC Output: The rectifier's electromagnetic isolation unit outputs floating DC voltage — no single-pole shock risk, no leakage on single-pole grounding.
Insulation Monitoring: Detects insulation status of the DC bus and all branch circuits, fully monitoring supply cable insulation.
Power Distribution Monitoring: The cabinet provides comprehensive smart distribution functions, including energy consumption statistics, rectifier module status monitoring and control, output branch status monitoring and control, and internal fault alarm monitoring.
Lighting Monitoring: The cabinet provides lighting branch monitoring and control plus diversified smart dimming functions.
Environmental Adaptability: Sealed design resists dust and salt spray, handling harsh environments with ease.
Quick Replacement: Rectifier modules support hot-swap replacement on fault—a single module failure won't affect power supply. Branch control modules also support hot-swap replacement, so one module's failure won't affect other branches.
