![]() Generally, any product which requires only a small motor (e.g. Thus, as long as the product gets current from a proper transformer, the motor inside will run at the correct speed. DC motors are not affected by the frequency mismatch, because the motor runs on DC (for which frequency is irrelevant) and the DC current is supplied internally by the product. power drill) will be a synchronous motor. hair dryer), or must drive something with great force (e. You will generally find that any product that contains a motor that runs at high speed (e.g. When such a motor made for 60 Hz receives 50 Hz, it runs at 5/6 speed. Synchronous motors are affected by the frequency mismatch. But.there are two kinds of motors that will be found inside electrical products, and one type is affected by the frequency, while the other is not. things that run fans, spin wheels, rotate things, etc. ![]() The only electrical products that need concern you regarding this frequency mismatch are products that contain motors (i.e. Transformers do not provide a conversion to US 60 Hz you are stuck with UK 50 Hz. Don’t try to draw more than what the transformer provides: you will be risking the health of you and your electronic components! So if you have three components drawing 30 watts each, get a transformer than delivers about 115 watts. Add up all the watts that every one of the components will draw that will be turned on at the same time, then multiply by about 1.25 for good measure, and that’s about the size you need. The more wattage required by the electrical item(s), the bigger (and more expensive) the transformer will need to be. you need to consider how many watts your transformer is providing (all transformers should clearly indicate this). From there you may want to plug in a US-style power strip and provide current for several products. The transformer will “step down” in voltage from 240 to 120v. (I’ve heard some of these smaller transformers can be found at American stores like Target for about ten dollars, but they may not be very good quality. In order to convert, you must use a transformer, which is a unit that you plug into the wall and then plug your American appliances into. There are four differences between using US appliances in the UK : the voltage ( US = 120V, UK = 240V ), the number of watts the product draws (different for each product), the frequency ( US = 60 Hz, UK = 50 Hz ), and the plug on the power cord. This website and its author(s) will not be held responsible for any accidents or lawsuits that occur from following this advice, it is not professional electrician advice. The UK has a completely different electrical standard, voltage, frequency and plug type. One of the most often asked questions is what electrical devices you can bring from the US.
