Hi Group, I have one of those scenarios where EMC meets product safety. For the purpose of RFI, I have a requirement to connect RF bypass capacitors from the input lines of a Low voltage DC (30V max, SELV) piece of equipment to PE. As I recall when I worked in ac voltage converters, we used to connect Y-rated capacitors between phase and PE.
Is it still a requirement that I need a Y-rated capacitor for this LV product or can I get away with a much smaller capacitor with a varistor in parallel? All comments welcome. I trust the wording is clear but please let me know if a sketch in word is required. Thanx in advance.
