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.
* A UN
correspondent reports C and F common in Kabul, but its likely a variety of
plugs may be used around the country. Some sources report Type D also in use. Other reports
indicate voltage variances from 160V to 280V.
*Outlets
typically controlled by adjacent switch. Though nominal voltage
has been officially changed to 230V, 240V is within tolerances and
commonly found.
Notes from
correspondents: a 'C' style plug can be used with 'E' and 'F'
receptacles. All double-insulated appliances are indeed fitted with
a 'C' plug, and can be used in any compatible receptacle (C E F and narrow
L). Type C receptacles are prohibited in Belgium.
*127V found
in states of Bahia, Paraná (including Curitiba), Rio de Janeiro, São Paulo
and Minas Gerais (though 220V may be found in some hotels). Other
areas are 220V only, with the exception of Fortaleza (240V). Outlets (click for more) are
often a combination of type A and
C and can accept either type
plug.
Type L
plugs/outlets may have different pin spacing. The smaller and closer
pins are for a rated current of 10 A, the bigger and wider pins are for a
rated current of 16 A.
The
"official" plug type is like type A but slightly shorter and without
holes in blades. Type A
and I outlets are common, and Type
G might also be found. Click here for photos and more
info.
Denmark's
connectors have slight differences from those used elsewhere. While
pin diameter and spacing is standard, outlets may have different housing
depths which could interfere with standard adaptors -- one report says
this is due to "childproofing." Also, Plug C fits into K-type
outlets (but not vice versa).
A UN
correspondent reports "power is poor in the country with frequent
brownouts and blackouts. I suspect that surges are frequent as we go
through a lot of surge-protecting power bars." Further he reports
than Type I
is common as much
construction is done by Australians; type C is common in building built during
Indonesian occupation; type E is
less common; type F is common in
offices but not hotels.
Type C plugs may be found on some
appliances, and will fit the Type E outlet. Type C outlets may be found in older
buildings. Type A may be found in older buildings but
is illegal.
*Inside the
capital city of Georgetown, both 120V and 240V at either 50 or 60Hz are
found, depending on the part of the city (50Hz most common). Actual
voltage may vary from area to area.
*Many (but not all)
modern electric outlets in Israel have larger holes that accept both Type
H and C plugs. Some extension cords and older outlets accept only
the Type H plug. One correspondent estimates a 50-70% chance that a
randomly selected outlet will accept Type C.
Type L
plugs/outlets may have different pin spacing. The smaller and closer
pins are for a rated current of 10 A, the bigger and wider pins are for a
rated current of 16 A. Both kinds are currently used and comply to
the relevant Italian (CEI) regulations. Some outlets have
overlapping holes to accept either older or newer types.
*Type F
likely to be found in offices and hotels. 110V power with plugs A & B was previously used but is
being phased out. Older buildings may still have this, and some
hotels offer both 110V and 220V service.
Type G*
found primarily in better hotels. Also, many of
major hotels chains are said to have multipurpose outlets, which will
take Australian 3-pin plugs and perhaps other types.
A
correspondent notes: "Plug type E can also be used (because the mains
outlets do not have the protruding pin). Plug type F can sometimes be used
but with reservation because in many places the mains outlet will not
allow to connect such plug as the outlets have smaller hole diameters than
F-plug pins."
*Outlets
typically controlled by adjacent switch. Though nominal voltage has been
officially changed to 230V, 240V is within tolerances and commonly
found.
Type F becoming more common as a result of
computer use. *Neutral and line wires are reversed from that used in
Australia and elsewhere. Click
