Incorrect voltage input

you could try replacing the power supply. if it still does not work, you probably fried the processor or motherboard. (or both). just make sure the replacement power supply has the same type of connectors on the power leads to the motherboard, hard drive, etc.

you will need a reducing transformer 220volts to 120 volts, you can find one at Radio Shack or Fry's Electronics., European countries uses 220volts, and the plug configurations are different from those of the USA.it is recomended to take one of these transformers with you when you travel abroad.

Unless the item has internal fuse, it is burned up.
Look for product manual.
Many times, there is a glass fuse rated for unit voltage.
Replace fuse.
Each fuse has specific markings.

UPS will provide constant voltage out put.
The average working condition of UPS is 170 to 270 volt.
Below the level may not work.

If the computer power supply is a 240 volt unit and you plugged into 110 volt mains the the computer should be OK.
Some power supplies have a voltage selection switch on the back of the power supply switch to 110 volts and it should work.
If the power supply is 110 volts and you plug it into a 240 volts mains then you will damage the power supply and possibly the computer as well.

The least of your problems would be a burnt out relay or internal switch which can be replaced at reasonable expense. In a worst case the motor or heating element "fried" and it'll be cheaper to buy a new dryer.
BTW 110 and 220 plugs are entirely different and a 110 plug cannot be plugged into a 220 outlet.

Rather than modifying the unit (which may not be possible), you should be able to locate a voltage transformer that will convert the 110 into 240. Many of these types of units utilize different power transformers depending upon the source voltage. If you'd rather not use an external transformer, request a source voltage change kit from Velleman. If they utilize different parts, the required parts will be included in the kit.

hello , i suggets you replace the power supply with a 110 v input boerd .
or do this if the damage is big replace the all sytem with a new one then get a voltage step down ie 220 to 110.

thank you

Please check Input Voltage 110 ~ 240 volts AC at rear or bottm side of unit. If same is written there, its Auto Voltage Operatable and can be use on 220Volts.
