Description
EMC requirements for electrical and electronic products are becoming increasingly important. Functional, regulatory, contractual and liability issues oblige manufacturers to produce equipment which is compliant with strict EMC requirements.

In common with all design considerations, addressing EMC early in the design process can save significant time and money. Inter-departmental co-operation is a critical factor in producing EMC compliant products. This 3-day course will show you how to design products which are right first time by building in EMC measures from the outset and ensuring that all departments are involved to enable effective teamwork.

The course encourages student participation with demonstrations and case studies.

Course objectives:

- To increase knowledge of EMC and understand how it affects electro-technical products.
- To understand how to apply this knowledge to enable cost effective and compliant design of products, systems and installations.
