U375-W Series Smart DC Lighting Distribution Cabinet
The U375-W Series is an intelligent lighting distribution system featuring a 380V AC three-phase input and a 375V DC output. It integrates advanced DC Power Line Communication (PLC) dimming based on Manchester encoding. Engineered in compliance with GB/T 3797-2016 and GB/T 7251.8-2020 standards, this series is ideal for large-scale applications such as tunnels and industrial parks. It supports versatile intelligent controls, including zonal dimming, full-area scene presets, and sensor-based automated dimming.
Product Features
High Efficiency & Energy SavingCentralized Conversion: Integrating dispersed driver units into the distribution cabinet increases overall system efficiency by 10%.
Advanced Conversion: Utilizing 3rd-generation SiC (Silicon Carbide) rectifiers, achieving peak conversion efficiency of ≥96%.
Intelligent Lighting Power Management: Features versatile smart dimming capabilities designed for on-demand illumination, effectively reducing energy consumption by up to 50%.
01
Safety & ProtectionFloating 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.
Insulation Monitoring: Real-time insulation status monitoring for the DC bus and all branch circuits ensures cable safety.
02
Intelligent MonitoringDistribution Management: Comprehensive statistics on power usage, status monitoring of rectifier modules, and internal fault diagnostics.
Lighting Control: Real-time monitoring and versatile control strategies for individual lighting branches.
03
Exceptional ReliabilityEnvironmental Adaptation: Fully sealed design with superior dust and salt-mist resistance, ideal for harsh environments.
Quick Replacement: Rectifier modules are hot-swappable for seamless replacement without interrupting the power supply, while branch dimming modules also support hot-swapping to ensure that a single module failure does not disrupt power delivery to other circuits.
