The US power standard is 110 volts at 60 Hertz. You may need to purchase an appropriate power supply for the UK power standard. Never use a power transformer designed for 60 Hertz on a 50 Hertz system unless it is specifically labeled as being OK for both. Some transformers designed for 60 Hertz can become extremely warm and overheat when run at 50 Hertz.

Even if the voltage and frequency match, you would still need an adapter to get the connections to match.
