Our company makes open frame linear and switch-mode component power supplies in the range of 5-500W. Applications include industrial, and medical equipment.
The sales distributor we use in Australia has contacted us asking for EMC documentation to support C-Tick marking of our products, as required by the ACA (Australian Communications Authority). They are asking for an EMC test report and declaration of conformity showing that the converter complies with the relevant EMC standard. I want to verify what, if any, documentation is required for a product like ours. I have copies of several EMC-related documents from the ACA web site. Unfortunately, I can't tell if component power supplies require the same level of documentation as completed systems. 1) It appears that the regulations do covers power supplies, as discussed in the ACA EMC FAQ at http://www.aca.gov.au/consumer/faq/emc.htm. Is this accurate? 1) What is the definition of a 'Converter'? The EMC FAQ located at http://www.aca.gov.au/consumer/faq/emc.htm says that "Converters that use linear technology fall within the scope of AS 1044 if they are designed for connection to a low voltage electrical supply". Does this mean that our linear-mode power supply (i.e., isolation transformer with bulk storage capacitor, series pass regulator, LM7805 regulator, etc.) must comply with that CISPR14-like standard, while the ITE-related end use may need to conform with a CISPR22-like standard? 2) Some of our power supplies were designed to meet only the conducted emission portion of the EMC specification, not the radiated emission portion. Therefore, we can't claim full compliance with the emission standard. Does this imply that the power supply must be redesigned, or no units can shipped to Australia? 3) Do we put the C-Tick mark on our products, or is this an issue for our Australian partner? ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
