Electrical power around the world

Digital Tigers international power compatibility

Digital Tigers is based in the United States, and offers all its products standard with U.S.-style power cables, with free international power cables available in most cases.

Stratosphere workstations, SideCars and Zenview displays are built with international switching power supplies that are compatible with most electrical systems in the world in the 100 - 240 VAC range (or greater). However, these power supplies still require a local power cable appropriate for the customer's country. In most cases, we are able to supply these cables free of charge as a service to our international customers. However, international customers should verify our supply of compatible power cables prior to order.

Exceptions: both UPS backup power supplies and speaker systems are built with hardwired U.S.-style power cables restricted to 120V / 60Hz power. We recommend that customers with incompatible local power standards buy their UPS backup power supplies and speaker systems locally. (Neither UPS backup power supplies nor speaker systems are warranted for use with add-on transformers.) We offer international customers a credit for the standard UPS system.

TABLE: Electrical systems in use in most countries of the world

The voltages listed below are the "nominal" figures reported to be in use at most residential or commercial sites in the country or area named. Most electrical power systems are prone to slight variations in voltage due to demand or other factors. Many former 220V countries have converted or are in the process of converting to the EU standard of 230V. Generally, this difference is inconsequential, as most appliances are built to tolerate current a certain percentage above or below the rated voltage. However, severe variations in current can damage electrical equipment.

The electric power frequency is shown in the number of hertz (cycles per second). Even if voltages are similar, a 60-hertz clock or tape recorder may not function properly on 50 hertz current. All systems described here use alternating current (AC). The plug types listed indicate all types known to be in use in that country. Not all areas of a country may use all types of plugs listed for that country, since there may be regional differences based on the power system in a certain area.
