The development of railway technology
The German motor vehicle technology series, the Canadian mobile car technology series, the French train technology series ans other rail transportation technologies represent the advanced level of the world. China’s rail transit technology has been introduced and developed in recent years, and it has reached the advanced level of the world, but the key traction control technology is still dominated by foreign products.
Since the construction of Shanghai 1 and Guangzhou 1 subway in the 1990s, urban rail transit construction in China widely uses the latest technology and equipment, has built a world-class technical level of urban rail transit system, but the rail transit technology is still in the stage of introduction, digestion, absorption and innovation.
In the 1990s, all countries in the world adopted the stepless speed regulating DC motor system or the stepless chopper regulating DC motor system with power electronic control. In1990, after the emergency of GTO, the insulator gate transistor (IGBT), the developed country metro began to adopt the AC drive system of straight – alternating frequency conversion and variable pressure regulating AC motor. Since the 1990s, all new subway lines, monorail and light rail lines have been used in the communication transmission system of IGBT module except Shanghai NO.1 subway. Compared with DC drive, AC drive can reduce the power consumption by 40%. The amount of brake shoe is reduced by more than half due to regenerative braking.
The metro type A car (car width 3 meters /3.2 meters) and type B (2.8 meters wide) are all widely used in the international general application of the non-swing pillow bogies. This kind of bogies has the advantages of simple structure, less spare parts, light weight and less maintenance. Bogies with two lines suspension damping structure, a series adopts metal rubber laminated structure, the department uses the air spring, and is equipped with automatic height adjustment valve, through the exhaust gas and gas supply, automatically adjust the vehicle floor height, with faces matching platform. All different types of vehicles, such as subway A, B, linear electric locomotive, monorail, low-floor light rail, etc., are produced in our country.
Recommended product series: DPM60-110SXX-EB\DPM150-110SXX-FA series.

12V AC to DC Converter Module: Efficient Power Supply Solution
When it comes to powering electronic devices, there are two types of electrical current that can be used: alternating current (AC) and direct current (DC). While most electronic devices require DC power, the power supply that comes from the wall outlet is typically AC power. This is where a 12V AC to DC converter module comes in handy. A 12V AC to DC converter module is a device that converts AC power into DC power. The module takes the 12V AC power from the wall outlet and converts it into 12V DC power that can be used to power electronic devices. The module is commonly used in a variety of electronic devices, including LED lighting, security cameras, and audio equipment....

Industrial AC-DC Converter for Efficient Power Conversion
Industrial AC-DC converters are devices that convert alternating current (AC) to direct current (DC) for use in industrial applications. They are designed to provide efficient power conversion, enabling industrial equipment to operate reliably and efficiently. These converters are typically used in industrial processes such as manufacturing, automation and control systems, and power distribution systems. The primary function of an AC-DC converter is to convert the voltage and frequency of incoming AC power to the appropriate DC voltage required by the equipment. This requires a complex circuitry that includes a rectifier, filter, and voltage regulator. The rectifier converts the AC voltage to DC while the filter smoothes out the output voltage, and the voltage regulator ensures the output voltage is maintained...
