This database contains over 33,300 pieces of detailed data (190KB, 70+ pages) on specifying and designing power supplies and line cords for use in almost 300 countries:

• Primary voltages, frequencies, and their tolerances.
• Plugs.
• Languages for manuals and product documentation.
• Approval marks and approval agencies.

The source material for this database was gleaned from 101:

• U.S. Department of Commerce books and web pages.
• British Standards Institute booklets.
• Books.
• Companies' catalogs, wall charts, and web pages.
• IBM/Lexmark standards and product documentation.
• Magazine articles, web pages, and other sources.

You may download a 38KB 9-page synopsis of this database from intpower.htm. It lists nominal voltages and frequencies, power plugs, and languages for the 200 countries for which we have the best data.

John started this database in 1990, and adds to it as he finds additional source material. Oscar started contributing to this database in 2001, as Lexmark's de facto linecord expert. Various versions of this database were used internally at IBM Lexington and Lexmark for about eleven years before it was first made publicly available through the Internet. John's book, Robust Electronic Design Reference Book, Volume 2, which came out in March 2004, contains a synopsis of this material in Appendix L, along with fullsize drawings on the most common plugs in Figure L-1.

This revision:

• Adds data from 41 additional sources.
• Adds recent approval marks, along with the names of the approval marks or the safety agencies that issue them.
• Adds Electric Current Abroad plug designations to the plug listings and plug drawings.

The number in parentheses after an entry (xx refs) shows how many times that particular piece of information has appeared in the sources listed. If we've found only one reference with that data, the abbreviation for that source document is in parentheses. A question mark after the abbreviation means that we do not trust this data, because the source has too many unique data items for our taste. Bold text shows the voltage and frequency, plug, and language that we personally would design to/recommend designing to for that country.

Disclaimer: Use this information at your own risk. Some nations, such as Brazil, have not standardized primary power or wall outlets across the country. Other nations are still in the process of switching from an old standard to a new standard. Even in developed nations such as the U.S., parts of some cities have unusual voltages/frequencies/wall outlets. When in doubt, contact your customer or a person who is familiar with your customer's sites.

To be approved and used worldwide, a power supply should:

• Operate on 90-265V 47-63Hz primary power.
• Have a detachable linecord (also known as a power cord or cord set):
  • Grounded appliances often use IEC 320 Sheet C14 appliance inlets, to accept linecords with IEC 320 Sheet C13 plugs.
  • Ungrounded appliances often use IEC 320 Sheet C8 appliance inlets, to accept linecords with IEC 320 Sheet C7 plugs.
• Be of double-insulated (EN 60950 Class 2) construction internally.

A power supply that covers just the low-voltage countries can:

• Operate on 90-140V 47-63Hz primary power.
• Be a "wall wart" with a #1 (NEMA WD-1 1-15P) plug
  OR
  Have an attached linecord with a #1 plug
  OR
  Have a detachable linecord with a #1 plug.
• Be of double-insulated (EN 60950 Class 2) construction.
