Did some further investigation into this. Looks like the device will actually handle both 115/230 VAC (as per the spec which I found on the Milwaukee web site). The only problem is with the socket used for the controlled device - (this sits between the mains socket and the controlled device plug, with a pass-through for the neutral and a switch wire (controlled via the controller) for the live) - which is a US type fitting. This is problem is easily solved using a couple of cheap travel plug adaptors.

Why bother? - the device is almost three times the price in Europe as it is in the USA. If I'm wrong - I could just get a 115 VAC solenoid and still save money!! I'll give it a try and let you know how I get on!
