World Voltages

Note: In the ever changing environment of technology, it is important to verify the data in the
tables below to see that it is current.

In designing electronics for international shipment, it is especially important to take into consideration the
electrical system of the country or even area of the country in which the product is to be used. Electrical
systems throughout the world vary in electrical frequency between either 50 or 60Hz. Additionally, the
commercially available power input can vary significantly within a geographic area.

In the early 1990's, the governments of the European Community decided to standardize electrical
frequency and commercial voltage to 50Hz. and 400 volts. This was considered a reasonable split
between the 380V used in mainland Europe and the 415V used by Great Britain and Europe's satellite
countries. To date, only a few countries have officially changed their systems.
