Can I connect a European HP5990 to the US power grid?? 210V-110V

Many manufacturers design equipment with varying voltages in mind, and may list an ability to handle input ranging from 110-240 volts, indicating that it will work in Europe and the United States. In addition, the equipment is usually rated at 50/60 hertz, and will function on either cycle. However, some devices, especially hair dryers, are designed to function at either 110/60 or 220/50. If this is the case, a voltage converter is necessary.
If this is the case, look at the wattage requirement of the device, which should also be listed. When buying a voltage converter, be certain to get one with a wattage which has a higher rating than the device you are plugging in, to prevent electrical malfunction. Some electronics also require more energy at start up than in a running or standby mode, and if this is the case the wattage rating of the voltage converter should account for 120% or more of the listed wattage need of the device....Setanta
