Hi Doug, First, I have to ask a couple of questions. You mentioned that this product will be CE compliant. If so and if this accessory is aimed at the EU, why then would it have North American NEMA 110V outlets? Or, does this product when CE marked have outlets acceptable for CE marking? Is it intended to sell these 110V output products (clearly not CE) into Europe to connect to this accessory? I'm not sure as to the US & EU safety standard that would apply to this type of product, however, the output should be considered a primary circuit and, as such, should meet the requirements for primary circuits. At 300W output and assuming an efficiency of about 80%, you should be seeing an input current of little more than 30 Amps. With such an input current you should be at least concerned about heating and fault conditions. Anyway, these are my comments and I hope this helps. Best regards, Ron Pickard [email protected] PS - To all, clause 1.1.1 of EN60950 (scope) says applicability exists for "mains-powered" or "battery-powered" (quotes are mine) ITE ...... with a RATED VOLTAGE not exceeding 600V. Does the "RATED VOLTAGE" here imply to the input, output, or either? Just a curiosity question to throw out.

This Inverter will be intended to be connected to the DC terminals of a 12 Volt automotive battery and has two North American 110V Outlets, it has a modified sine wave output, and is spec'ed to provide upto 300Watts of AC power. After looking at available off the shelf designs I found some that have some CE declarations, but after looking closely at these I found no mention of compliance to any Safety regulation but only EMC. My question is this, is it because the inverter has a low voltage input and they do not have to comply to a standard like EN61010 or UL1950, or is this something the manufacturers haven't addressed because no one has ever asked? ---------------------------------------------------- Douglas Best Compliance Technician IFR America's Inc.
