BLOCK — a family company with a bright future, a reliable brand

When it comes to perfect voltage solution for systems and plants,  BLOCK has been a strong global partner of industry and commerce for decades . Since the launch of the blue PCB transformers, the entire electronics industry has come to appreciate our brand’s reliability and supply security. In more than 80 years of company history, the company expanded into one of the world's leading manufacturers of transformers, power supplies, reactors and EMI filters. And to keep it that way, BLOCK consistently focuses on controllable, fast and reliable production within the company to maintain the highest quality standards. That is both the case at our headquarters and production site in Verden as well as in the production facilities in USA and China. Together with the increasingly important development center with more than 80 engineers and technicians, BLOCK not only offers the extensive standard portfolio in stock, but also fast customization or new development of your products. Thus, after only three weeks BLOCK custom-made products can be certified and leave the production sites in Verden. BLOCK unites research, development and production under one roof. From winding products to filters to power supplies and software development, our know-how can be found at every stage of the development and manufacturing process.
