EMC tests during development

The fully equipped BLOCK EMC testing laboratory, with its trained staff, not only tests and measures the company’s own products. BLOCK also offers EMC-relevant tests as a service to external customers. The laboratory is certified to DIN EN ISO 9001. The mobile EMC laboratories complement BLOCK's scope of services.

All products, such as transformers, reactors, power supplies and EMI filters, are developed in close collaboration with the customer and produced in line with market needs. They can be found wherever reliable mains interfaces are required. Our EMC testing laboratory acts as an independent business division. The laboratory focuses on EMC services in the field of generic technical standards for products in the capital goods industry.
