LED undercabinet lights but 240v inputs
Sounds like you should just get a transformer to transform your 240v main to whatever the LED drivers are looking for.  Without more detail, I'm not sure what the LED's are designed to take in.  

It sounds like your LED drivers are going to convert a less-then-240 voltage AC feed down to the couple of volts DC that the LEDs are going to use.  Since you are putting these under cabinets, you could mount the transformer up and out of the way where you couldn't see it.

I'd look at one of the online electronic parts suppliers (like DigiKey or Jameco) to find the transformer you will need.  You shouldn't have to get to big of one since you are only powering LEDs.
