A frequency converter, also known as a power frequency changer, is a device that takes incoming power, normally 50 or 60 Hz and converts it to 400 Hz output power. Different types of power frequency converters exist, specifically, there are both rotary frequency converters and solid state frequency converters. Rotary frequency converters use electrical energy to drive a motor. Solid-state frequency converters take the incoming alternating current (AC) and convert it to direct current (DC).
Standard commercial utility power is alternating current (AC) power. AC refers to the number of cycles per second (‘hertz” or Hz) that the power fluctuates, positive and negative, around a neutral datum. Two standards exist in the world, 50 hertz and 60 hertz. 50 Hz is prevalent in Europe, Asia, and Africa, while 60 Hz is the standard in most of North America and some other countries (Brazil, Saudi Arabia, South Korea) around the world.
There is no inherent advantage to one frequency over another frequency. But there can be significant disadvantages. Problems occur when the load being powered is sensitive to the input power frequency. For example, motors spin at a multiple of the power frequency. Thus, a 60 Hz motor will spin at 1800 or 3600 RPM. However, when 50 Hz power is applied, the RPM is 1500 or 3000 RPM. Machines tend to be speed-sensitive, so the power to run them must correspond to the design RPM intended. Thus, a typical piece of European machinery needs 50 Hz input, and if it runs in the United States, a 60-to-50 Hz converter is required to convert the available 60 Hz power to 50 Hz. The same applies vice versa to convert 50 Hz power to 60 Hz. While standard power ratings and capacities exist for frequency changers, our converters operate over a range of voltages from 100V to 600V. The most commonly specified voltages are 110V, 120V, 200V, 220V, 230V, 240V, 380V, 400V, and 480V. Because our standard and custom design capabilities can meet a range of power system needs, Georator is your supplier for frequency to voltage converters.
