In today’s power supply for servers, machines and other technical equipment, AC voltages at typically 230 V or three-phase systems still dominate. This architecture has evolved over time but is gradually reaching its limits. Due to the increasing power demand, new load architectures and the desire to improve efficiency, there is growing interest in DC networks operating at higher voltages.
Read articleReliable switching is essential for safety and availability in high-voltage systems. The HVR10 high-voltage relay from E-T-A combines high switch-off performance, robustness and maintenance-free operation in a compact design. This makes it the ideal solution for the most demanding high-voltage applications.
Read articleEfficiency, sustainability and digitisation are key topics in the utility vehicle industry and are changing on-board electrical system requirements: Advanced electrical components for sophisticated systems in modern commercial vehicles have become essential.
Read articleAn increasing number of comfort functions in vehicles must be supplied with increased power. The obvious solution is to enable more power by increasing the operating voltage. The flowing current remains unchanged so that power loss, cable cross-sections and cooling systems must not be adapted.
Read articleHigher voltages for the active technology supply in the telecommunication technology area have been discussed for years. While existing systems are normally not retrofitted due to the high costs involved, this option is quite popular for newly built control rooms and data centres.
Read articleElectrical cars, buses and delivery vehicles are a common sight today. However, new solutions are needed to make them even more desirable and economical and appropriate for other applications, such as long-distance trucks and coaches.
Read articleHigher DC voltages are the next technological evolutionary stage in the industrial sector. But these networks place completely new demands on overcurrent protection. We are already working on solutions for these future challenges.
Read articleElectronic vehicles are already a mass market. Relatively long charging times, expensive batteries and rather low ranges are still critical challenges, but are being improved quickly. We also support the development of sustainable mobility and provide some insight into current and future high-voltage battery switching and protection concepts.
Read articleModern utility vehicles need modern components in their on-board electrical systems. Trends such as efficiency, environmental-friendliness and digitisation are driving the commercial vehicle industry and have impacted on-board electrical system requirements. E-T-A is constantly developing components with this in mind and offers solutions in the field of power and high-voltage [...]
