Functional Features

Mesh circuit design ensures stable product operation
The light board adopts a "mesh" circuit design. When a LED lamp bead fails, it automatically isolates the fault point to ensure that the remaining light beads work normally, maintaining a stable overall display effect.
European standard power supply, more energy-efficient and environmentally friendly
It uses an independently designed Euro standard power supply with excellent energy conversion efficiency and a power factor of up to 0.98, significantly reducing energy consumption and being highly energy-efficient and environmentally friendly.
Constant current drive design, with long service life and low maintenance
It adopts constant current drive technology to ensure stable working current, extend the lifespan of the lamp, and effectively reduce maintenance costs in the later stage.
Excellent electromagnetic compatibility, enhancing device stability
It strictly adheres to European electromagnetic compatibility standards, meeting the strict requirements of developed countries. The total harmonic distortion is less than 10%. It effectively reduces interference to the power grid and other equipment at the intersection, significantly enhancing the overall stability and lifespan of the equipment at the intersection.
Compatibility design for enhanced maintenance efficiency
The built-in countdown timer supports three adaptive operating modes: communication mode, trigger mode, and learning mode. Designed to be compatible with over 99% of mainstream domestic and international traffic signal controllers, this feature significantly reduces installation and post-installation commissioning efforts, thereby enhancing overall equipment maintenance efficiency.
