Voltage Selection

Torch Computers 55” LCD screens, model Series EN083KXXX series, are designed to
work on both 110-120 VAC (60Hz) and 220-240 VAC (50Hz) 325 watts mains electricity
supplies.

Normally, the screen will be delivered to the end user with the correct voltage for the
local supply already set.

Type UK – (5amp fuse fitted) used in United Kingdom, Singapore, Hong Kong, and
some other countries.

The other end of the cable is an IEC socket, type C13.
This cable is for use on 220-240 VAC, 50 Hz

Type Schuko – used in many European countries
The other end of the cable is an IEC socket, type C13.
This cable is for use on 220-240 VAC, 50 Hz

Type USA – used in USA, Canada, Taiwan and some other countries
The other end of the cable is an IEC socket, type C19.
This cable is for use on 110-120 VAC, 60 Hz

For countries with 220-240 VAC supplies, but which use neither the UK plug nor the
European (Schuko) plug, the user should obtain a professionally-made power cable with
the local plug at one end and the IEC type C13 socket at the other, which can then be
used in place of the 220-240 cables supplied.

Countries with 110-120 VAC supplies often use the USA type plug, in which case the
type USA cable supplied can be used. (See above)

However, if the local plug is not the USA type, then a cable must be made with the local
plug at one end and an IEC type C19 socket at the other end.

WARNING

The IEC type C13 socket MUST NOT BE USED WITH THE TORCH COMPUTERS

55” SCREEN WHEN THE MAINS SUPPLY VOLTAGE IS 110-120 VAC

NOT ON 110-120 VAC

NEVER connect the square C19 connector

to a 220/240 VAC type plug

It is extremely dangerous to apply a voltage

of more than 120VAC to the input socket

designed for this C19 connector
