1. Our bare board power supply uses high-quality circuit boards to ensure the electromagnetic compatibility and anti-oxidation performance of the circuit boards;
2. Our traffic light power supply uses intelligent chips to ensure stable power supply performance, long-term operation without heating, and is guaranteed for use on roads;
3. Our 12v2a traffic light power supply is all purchased from imported high-quality electronic raw materials to ensure quality. The probability of failure of dozens of customers and millions of products is less than 1‰;
4. Each 12v2a traffic light built-in power supply will be coated with a layer of protective paint, which plays a good role in protecting the circuit board, with fine workmanship and long service life;
5. This 12v2a bare board power supply is affordable and has a 3-year warranty. The price is the lowest in the industry and the quality is the highest in the industry. It is a power supply with great cost performance;
6. This bare board built-in power supply is more energy-saving and environmentally friendly to use. Traditional external power supplies require a large number of wires to be connected, which increases construction costs and daily maintenance costs, while built-in power supplies can be charged through clean energy such as solar energy, reducing power consumption, which is conducive to saving energy and reducing energy pollution.

 

 

Traffic light built-in power supply is mainly used in traffic lights such as traffic lights, pedestrian crossing lights, tunnel lights, and high-speed indicator lights on urban roads. In daily traffic accident prevention, these lights play a vital role. They can effectively direct vehicles and pedestrians to avoid accidents such as jaywalking and accidental collisions with cars when crossing the road. Built-in power supply technology can make the lights brighter at night and can be remotely controlled through a wireless signal control system, greatly improving the controllability of traffic lights.

 

The power supply of traffic lights is an important part of modern urban traffic management. With the increasing traffic and pedestrian flow in the city, traffic lights need to have not only basic characteristics such as reliability, controllability, and durability, but also high value-added characteristics such as power saving, environmental protection, and intelligence. The built-in power supply technology is the key to making traffic lights more advanced, more intelligent and more convenient.

 

 

 

The built-in power supply of traffic lights usually uses a DC power supply, and its core part is the power converter. The power converter is the key to converting the AC voltage of the mains into a DC voltage. When the AC voltage of the mains enters the power converter, it first passes through a device called a rectifier to convert the AC voltage into a DC voltage. There will still be some fluctuations and ripples in the rectified DC voltage. In order to make the DC voltage stable and reliable, the power converter needs to further filter the DC voltage to make the DC voltage more stable. Once the DC voltage is stable, the power converter can start to provide power for the traffic lights. The output voltage of the built-in power supply of traffic lights is usually 12V, 24V, and 48V. Through these voltages, the built-in power supply of traffic lights can provide driving power for the LED lights in traffic lights, realize light display, and control traffic flow. At the same time, the built-in power supply of traffic lights also needs to meet the requirements of stability and reliability of light display, and adopt different parameters such as power and current in different application scenarios to meet the needs of traffic management to the greatest extent. Under normal circumstances, the built-in power supply of traffic lights will continue to work, provide stable power for traffic lights, and ensure the normal operation of road traffic. Once a fault occurs, the built-in power supply can also alarm in time and automatically switch to the backup power supply to avoid traffic accidents.

 

In general, the built-in power supply of traffic lights is an important part of ensuring the safe operation of urban road traffic. By understanding its working principle, we can better understand the operating mechanism of traffic lights, thereby better ensuring the safe operation of road traffic.
