110V 240V AC LED VMS Signs Matrix Screen Dynamic Traffic Message Sign
Matrix Screen Traffic message sign Road Dynamic VMS boards 110-240V AC 65kg/m²
Minimized power consumption
When a screen is displaying message, for most cases, a large proportion of screen maintain black, Our product is able to detect it
and turn this area into sleeping mode .
Second optical lens
It is well know that vms upper viewing angle makes light pollution 505 loss, By applying second lens, we can manufacture 0 ipper
viewing angle 0 light pollutions and 0 energy loss
Lighting shock procetion
We have equipped lighting shock component of industrial level, High quality components include direct-lighting proctection, signal
protection. power surge protections
Dual voltage Input
Due to lighting chip difference, red/amber led has lower threshold voltage to light up than green/blue LED,so we applied dual
voltage chhannel to drive two types of LEDS, surplus enrgy is saved by this technology
Large storage memory
The build-in flash emory can strores as many as 2000 images and characters at a time
High Ingress protection
Our cabinet is fully sealed to enure ingress protection level up to IP65
Automatic/manual brightness control
Our digital photo sensor supports as many as 256 dimming levels with outside luminace range from 1 lx to 65535lx,which enables our
display screen to adjust to appropriate luminance level according to outside environment luminance reading will also be reported to
traffic control center
Double Layer door heat dissipation without fan
Double layer door housing, heat dissipation by aluminum conducting, which makes the MS internal temperature be low, Low temperature
can improve all components performance, more energy saving
