DC,

The AC adapter I have for my MX-3000 certainly is. Have an MRF-250, but not too sure about the adapter (not plugged in at the moment). I can check later on and will update you. On the other hand, they are cheap chinese manufactured adapters, so you should have no problem getting an equivalent replacement in the 220/240volt world.

However, be warned about the software issue and purchasing from Auth. Distributor, or face not being able to get software updates/ir database updates. A hot topic of discussion at the moment. Last thing you want is a new paperweight!
