Hi Group, Our financial transaction terminals are mostly used in the commercial area e.g. shops and offices, which use a separate AC/DC power supply block connected to the mains There is a requirement for these same products to be used in vehicles e.g. Taxis and Buses. These would use the power from the batteries possibly from the cigarette lighter holder (12Volts). I have obviously had to design in additional filter circuitry to account for this type of DC Supply source.
My question is, will there be additional EMC and Safety requirements in Europe or North America (other than those already approved for use in commercial areas) for vehicle/mobile use? Already Approved to: EMC: EN55022 Class B, *EN55024, EN6100-3-2, EN61000-3-3, FCC Part 15, ICES-003 Safety: EN60950 (also UL/CSA) *The only additional test I can think of is for the EN55024 to include the DC Power Port tests (excluded before due to the terminal being supplied from an AC/DC power source). As usual I look forward to your invaluable replies.
