What street lamp controller is 400 color the timer

Type 400 three color the timer, the domestic many manufacturers have discontinued, most with 800 * 600 or 1200 * 900 countdown timer, but in practical engineering, a few small intersection needn't so big of the timer, can increase the capital projects, so choose 401 countdown timer is heavy

many domestic manufacturers have stopped production of 400 type three color countdown timer. Most of the 800 * 600 or 1200 * 900 countdown timer. However, in practical engineering, a few small intersection don't need such a big countdown timer, this will increase the cost of construction project. Therefore, choose 401 countdown is a cool choice. On the highway and 401 countdown timer, used for speed measurement and display. Does not mean low quality, low price because of our production technology is complete, a production batch 500 sets, spare parts cost is relatively low, in addition to welding, cutting, automatic wave soldering and machine production, greatly reduces the labor costs, so prices low. The quality of the products in the process of planning, 70% and 20% in production, 10% in the aging test. We lean improvements were made in these three aspects. Product description: stroke style shows two digital countdown red, yellow and green. Because in China, yellow light is usually less than 6 seconds, so there is no yellow light on the left, there is no yellow light on the right. Lamp beads made of enough materials. Each stroke consists of 12 different colors of light bead, and three rows of double arrow. In the two Numbers to have 168 168 red light and green light bulbs, 84 a yellow light. The number of lamp bead is larger than that of parallel connection. Even a single lamp bead damaged due to disrepair, also won't affect all appearance. In addition, our company adopts series-parallel mixed constant current drive circuit for power supply equipment, ensure the service life of the LED lamp bead. Lamp bead adopt Taiwan famous brand of leds wick. There are two ways to choose from: self learning and communication, communication, in particular, can be easily connected with the signal, the implementation cycle and operation time. The second is the use of scenery: with the emergence of intelligent control occasions, as well as to enhance the efficiency of intersection traffic, some cycles uncertain situations such as induction control, adaptive control, bus rapid transit control, pedestrian street begging, etc. The countdown screen through signal connection needed to correct the idea of traffic participants and expected time of variable cycle use. 3. The introduction of the technical parameters of the traffic light shows three colors: red, yellow and green. Red light wavelength: 620 ~ 625 nm: yellow light wavelengths of 590 ~ 595 nm wavelength green light: 500 ~ 505 nm light life: ge; 100000 hours of homework forms: self-study and ac adjustable power rating: le; 20 w center light intensity: not less than 150 CD, no more than 400 CD, in the other direction - 45 150 CDS protection grade: IP54 perspective: ge; 30 degrees; Visual interval: ge; 500 meters installation method: horizontal working temperature: - Working voltage: 40 ℃ ~ + 85 ℃ (DC12V / 24 v, communication 220 plusmn20%) v( Optional) Warm function: empty air relative humidity of 5% ~ 95% ( No condensate) Insulation resistance: more than 10 ohms; Performance specifications: meet GB14887 - And GA/T508-2011 2004 industry standard structure size: 800 mm * 600 mm * 140 mm ( High * width * thickness)
