Application-compatible power supply are necessary for a future-oriented infrastructure, whether it be for telecommunications or train technology. With an input voltage range of 230 V AC to 400 V DC, the new Trio Power power supply offers a high-power density, parallel mode, and a highly durable electrical and mechanical architecture. As a result, it completes Phoenix Contact’s extensive line of power products and is perfect for infrastructure transitions, such as those in train technology.
Digital signal towers: new decentralized structure for railway technology.
Denmark, Norway, Germany, and other nations have decided to digitalize their railroads in order to advance the development of the European Train Control System (ETCS) and digital control tower technology. Along with further network extension and the employment of cutting-edge technologies, digitization is a crucial component in modernizing the rail system and, more importantly, in boosting performance.
German trains will need to adapt for a digital future, moving from traditional signal technology to radio-controlled train operation and utilizing cutting-edge technologies like artificial intelligence. Such technologies will enable fully automated train operation, real-time control, and accurate location in the future. Deutsche Bahn and the German Railway Industry Association established this industry wide Digitale Schiene Deutschland (Digital Tracks in Germany) program to accomplish this.
It is vital to upgrade not just the systems themselves but also the infrastructure, control, and safety technology in order for the digital technologies to coexist peacefully. By 2035, the integrated command and control system (iLBS), digital control towers (DSTW), and the full rollout of the ETCS will have completed this fundamental reform.
Increased capacity, optimal use of the rail network, and the change of transportation will all be significantly aided by modernization.
Obstacles to implementing railway technology
It is significant to remember that the components for railway technology are subject to tremendous stress in addition to the technological and structural constraints. Particularly when it comes to solutions for switch, signal, and barrier management as well as communication technologies close to the track, a sturdy component design is crucial.
Why do power supply in control cabinets near to railroad tracks need to be so strong? High needs are brought on by harsh climatic factors including extreme heat or cold, dampness, and dust. A high level of interference and vibration resistance is also required due to the high voltages and vibrations near the control cabinets. Long service life and a compact, low-maintenance design are further prerequisites for success in railway technology applications. It is necessary to adhere to the applicable criteria.
The design of systems and infrastructure in German railway technology focusses on telecommunications technology. In the future, 48 V will replace the 24 V operating voltage currently used for controllers—such as for switch controls and an extra 48 V voltage level—as the typical main voltage.
Trio Power Supply: Robust and reliable
Phoenix Contact’s Trio Power power supply exceeds exacting standards and was created primarily for use in infrastructure applications. The new power supply is ideal for use in these applications due to its shock and vibration resistance and sturdy mechanical and electrical architecture. Use the IEC 60068-2-64 standard and the railway-specific DIN EN 50125-3 standard to measure the equipment’s vibration resistance. This indicates that the equipment functions dependably even when traveling very quickly.
The new power supplies’ wide temperature range allows for a significant degree of flexibility in terms of potential applications. When exposed to temperatures between -25 and +70 °C, the power supply units are dependable and produce high power.
The Trio Power power supply has strong mechanical components as well as dependable and enduring electronics. The result is that the devices are input-side voltage-proof up to 300 V AC and 420 V DC. Another safety feature is overvoltage protection VP (OVP), which restricts overvoltage to 58 V DC. Furthermore, use control card with a protective lacquer covering to use the devices on 48 V applications subjected to heard weather conditions.
Use Trio Power supply in numerous supply networks worldwide as they come complete with an AC and DC wide-range input.
The power supply contain a dynamic power reserve that allows them to start heavy loads with reliability. For up to five seconds, they provide 1.5 times the nominal current. They also guarantee a high level of energy efficiency due to their high efficiency rating. Link multiple power supplies to generate more power. The devices’ enhanced load distribution allows for parallel operation for increased power and redundancy. Reduced inrush current improves availability even more and makes primary protection much simpler.
Challenges in telecommunications and infrastructure technology
Numerous applications, including artificial intelligence (AI), autonomous driving (Car2x communication), and intelligent production (Industry 4.0) need a quick, efficient, and secure infrastructure.
The existing 5G technology is being expanded to deliver this, and the follow-up technology is already off to a start.
The pressures on technology and systems are increasing as mobile data traffic between smart devices gets faster and more intense. Design network and communication technologies for infrastructure in order to be future proof.
Autonomous driving illustrates these connections. Share maximum amounts of data in real time between the vehicles and the transportation infrastructure to reduce traffic accidents Communication systems need powerful computers and operate at rapid rates to transmit and assess data.
The forthcoming 6G technology will have exceptionally fast data rates, albeit at the expense of transmission distance. The terahertz waves utilized for 6G also have wave properties that are more similar to infrared light than microwaves. The likelihood of redirected and obstructed waves passing through objects increases, particularly in urban settings. Future infrastructures will need numerous sending and receiving technologies to handle these issues.
Ensure a compact, maintenance-free, and environment-proof power source, such as a Phoenix Contact’s Trio Power with a wide input voltage range and 48 V DC voltage by using a dependable power supply on these decentralized systems, such as radio masts and transmitting and receiving systems.
