All
The "voltage rating" statement to my understanding is originally a
safety measurement to determine total current draw from a device so you
don't burn up your wall plugs (hence rated). That measurement was done
on the input voltage with load. That leads me to believe that the
"voltage rating" is determined from the input voltage measurement and
not the output voltage. Its a good argument but I would still line up
my ducks and keep trying to comply with RoHS.

Thank you Chris.
I was originally of the same opinion. But now I'm not so sure.
Article 3(a) says "designed for a voltage rating." It isn't clear to me
that this means "supply voltage." Also, in the EC's Frequently Asked
Questions document, Section 1.2.2 uses "piezo-electric ignition (> 1500
V)" as an example of a product outside the scope of RoHS. Where's the
supply voltage in that? Hit it with a hammer and it produces a spark. :)
Opinions please.
Regards,
Dane

No - it means the rated supply voltage for the product, otherwise we'd
all just stick a high voltage circuit in our products (and many products
already include such for displays etc.)
You ain't going to squeak out of it that easily I'm afraid :)

I want to make sure I correctly understand the scope of RoHS.
According to Article 3(a), if a device I market operates at or above
1000vac or 1500vdc, then that device is outside the scope of RoHS. It
does not matter if the high-voltage circuit is an input voltage, an
output voltage, or a voltage strictly internal to the device. Is this
correct?
