While the United States operates on a 110/120 volt, 60 Hertz system, the electrical system in Europe is 220/240 volts, 50 Hertz. In fact, the majority of the world, including Europe, the Middle East, and Africa, commonly runs on 50 Hz Alternating Current. It is important to know whether your OCONUS unit can operate outside of the US. Our international voltage section can help you decide. We've listed units specially designed to run on international voltage, including shredders, CD/DVD and keytape destroyers, and more. For more information, be sure to contact our international experts about different models and electrical requirements.
