Hello Group, Most of my designs have been engineered for the 'e' mark i.e. vehicle automotive EMC. This means the front end is ISO 7637 (transients) compliant.
I now have a requirement to extend the operating environment to any 12-30V DC power supply running off mains, in a bid to CE mark the product. I believe I need to perform ESD and RF emissions and immunity, but what about the Fast Transients and Surge tests? Is my product exempt because it does not actually connect to the mains supply, and if so, is there a requirement I can place on the user's power supply (apart from the usual tolerances) that in someway guarantees that any EFTs and Surge voltages are dealt with satisfactorily i.e. not coupled through? Would appreciate your advice.
