MODERN Frequency Converters are available in several different configurations to suit any frequency conversion need. Inputs and outputs are available in any combination of 50, 60, and 400 Hz. Frequency converters are very commonly used to test products designed for use in a different country before it is shipped. Using a frequency converter allows you to precisely emulate the grid power of your target environment in a controlled laboratory setting. They may also be employed when powering machinery from overseas.
