The modular build uses standardized LED components for straightforward installation. Timer and countdown customization, OEM/ODM customization and batch supply are supported; contact the supplier with your demands and drawings.
Use the listed values to compare the signal against site supply, visibility needs and outdoor operating conditions.
The model pairs full red, yellow and green LED panels with red and green countdown displays. Each full panel uses 204 LEDs, while each countdown display uses 128 LEDs. Confirm whether the project requires countdown timing on both phases.
Operating voltage is AC185V–265V, 50/60Hz. Full red, yellow and green panels are rated at ≤19W each; red countdown is ≤10W and green countdown is ≤12W. Match site supply and load planning to these values.
The housing is made from PC (polycarbonate) and die-cast aluminum, with an IP53 rating and multiple seals for water resistance. The ambient range is -40℃ to +80℃ for outdoor road environments.
A 30° viewing angle left, right, up and down and a visible distance of ≥500m support approach visibility. Compare mounting height, approach speed and sight lines against these figures during layout planning.
