Protocol Intro.
Modern rail infrastructure presents new challenges for freight and passenger transport solutions designers. The passenger rail system requires mobile office communication functions that support home infotainment. The freight railway system requires monitoring and control functions to ensure the safe and timely delivery of all goods on the vehicle. Both passenger and freight transport systems require reliable, high-performance power systems to achieve the necessary safety, security and security measures (vehicle and station). To meet these new needs, new DC-DC power converters must have higher power density, higher efficiency, lower cost, and be robust enough to meet the stringent requirements of on-board rail applications.
In case, the modular power components and complete power system provided by Good-choice are widely used by rail transit customers to create solutions for various railway applications. In this demanding market, we provide long-term successful service to our customers, and our understanding of railway standards and regulations, inspired us to design an upgraded new generation of on-board rail power supply: comprehensive isolation regulator DC-DC converter series DCM.
Advantages
DCM is the future of the evolution and development of rail power supply
The DCM series isolation voltage regulator DC-DC converter module is based on 20 years of proven successful experience in the railway industry, which can fully meet the needs of modern railway applications.
The DCM comes in two different package sizes: 2223x7 mm and 3623x7 mm, with the input voltage fully meeting all global orbital standards.
Including a wide range of 43-154VDC. and a narrow range of 18-36VDC, this series of products not only provides solutions optimized for 60-320W power levels, power density up to 653W / in³, but also can generate isolated DC output according to the application requirements.
The DCM converter uses a high frequency zero voltage switch (ZVS) topology to provide up to 93% efficiency in the entire input voltage field.
