Version for the American market: The power supply unit only accepts 110 volts.

During the first attempt to hook up the system from Koolance to the mains, a further obstacle had to be overcome. The power supply unit in the product we received was only designed for 110 volts - this is not much use for our European lab, and the version we tested didn't have a conversion switch. We fixed ourselves up with a voltage converter, but you should be aware of this issue upfront. Koolance does, however, offer a version for the European market, which includes a power supply unit for 230V. You just have to make sure to get the right version of the product depending on which region you are in.
