BLOCK Transformatoren-Elektronik GmbH has been a strong partner of industry and trade worldwide for decades when it comes to the perfect voltage for systems and installations. In over 80 years of company history, the company has expanded to become one of the world's leading manufacturers of transformers, power supplies, chokes and EMC filters. The company has 1,200 employees worldwide and is active at four production sites and 38 national and international agencies around the globe. 
BLOCK consistently relies on controllable, fast and reliable production within the company, in accordance with the highest quality standards. This is the case both at the headquarters and production facilities in Verden as well as in the production plants in the USA and China. Together with the increasingly important development centre with over 60 engineers and technicians, BLOCK also offers rapid customisation as well as new product development in addition to the extensive standard portfolio in stock. BLOCK combines research, development and production under one roof. From winding materials and filters to power supplies and software development, our know-how can be found at every point in the development and manufacturing process. 
In this project, BLOCK is developing efficient DC-DC converters for the auxiliary power supply and evaluating how these devices can be easily and cost-effectively integrated into communication systems. In addition, medium-frequency transformers are being developed for the high-power DC-DC converters used in the project by the other project partners. A concept for a service socket rounds off the tasks in the project.
