whoa whoa whoa!!!! There's only 3 leads? Do they connect the output - to the neutral? This is very dangerous, you really have to be careful about how you wire this up, and also how the power supply socket is wired... if the electrician reverse wired the socket, this could lead to a dangerous situation. BE CAREFUL!
Yes, the input is rated at 85 - 265V, so you can hook it up to any house power socket (just like ronv said), keeping in mind you don't electrocute anybody!!!
I'd really like to see a schematic or wiring diagram of the board.
