Hi Barry. You wrote: <Muriel has clearly defined his EUT=his product. Your first scenario expanded the definition of EUT to (Product + a dedicated transformer). Is it appropriate?>
I've been here before.... The reason for making the distinction between use at 110V and 220V is precisely because someone is going to supply a Tx for 110V use, so the effect of that Tx can be taken into account. I once tested some 110V production equipment for a company, wrote all the documentation, filled all the certificates, etc. etc. Had to use some big filters to keep the SCR noise down at 150kHz to 600kHz. Then I visited them when they were packing some for despatch, and they put a 2kVA transformer in the case. "What's that?" I asked... "Oh, all the machines go out with those, we only sell to the UK and Europe." I retested, and was able to take away a 70 UKP filter and save them a fortune in parts and labour. I've had a few like that. Chris Dupres Surrey, UK. --------- This message is coming from the emc-pstc discussion list.
