110-220 volt voltage converter power transformer 220 volt voltage converters 240 ...run on 120 volt 60 cycles (60hz) and most of the worlds run on 220/240 volt ...

There are products called Step Up transformers/Step Down (Voltage Converters) that can be used. We use these For our 220VAC Australian manufactured lasers when we need to run them in a Dr.'s office that only has US 110VAC.

Info from a website:
Electrical voltage in USA is 110 voltwhereas; the voltage in most of the foreign countries is 220V to 240 volt. A voltage converter / transformer, also known as power converter are usedto convert electricity coming out of the wall to match the voltage of yourdevice. These Voltage transformers or converters can be used safely withRefrigerators, Microwaves, Juicers, Blenders, Coffee makers, Power Tools,Stereo Systems, TV's, Video Games, DVDs, Hair dryers, Chargers, computersand other electronics when travelling abroad..

Remember to leave at least a 100-percent margin for power surges/spikewhen buying a transformer. Some items, such as Televisions, computermonitors spike when you turn them on. For these products you need to buy avoltage converter transformer that is at least 3 times the items capacity.Power tools, laser printers and heating appliances like coffee makers,toasters, microwaves, Halogen, Fluorescent bulbs you must leave a marginof 3-4 times.

Voltage transformers are made to convert single phase 110 or 220 volt.American 220 Volt consists of 2 phase of 110 Volt and European 220 Voltconsists of 1 phase of 220 volt.

Volts x Amps = Watts (i.e. 110V x 0.5 AMPS = 55W). Please make sure not torun any appliance with higher wattage then voltage transformer's wattage.This might damage both: your appliance and the transformer!

I hope this helps.

PHmaddnes Transformer Purchase Guide

If you consider doing this the first thing is SHUT THE MAIN BREAKER OFF. Use an auxiliary light source to see when working in a dead panel. Always keep in mind an ARC FLASH ACROSS HOT MAINS HAS ENOUGH HEAT TO PEAL THE SKIN OFF OF YOU. Before an explanation of how to do it you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 240 volt receptacles and if you plug any 120 volt device into them, the 120 volt device will be destroyed. That said OK, any 120 volt outlet can be changed to 240 volt by removing the 120 volt circuits neutral, re identifying the white wire with red or black phase tape and connecting it to a new 2 pole 15 amp breaker. The maximum that this circuit will now load up to is, on #14 wire at 80% = 12 amps at 240 volts. The 120V receptacle must be changed to a 15A - 240V receptacle so that 120 volt devices can not be plugged into it. Never use 2 single pole breakers together because code requires that on a fault trip both legs of the 240V circuit must be disconnected simultaneously.

Voltage converter buying guide. Voltage Transformer Buying guide.Voltage converters also known as voltage transformers are devices that convert foreign electricity to power devices from different parts of the world. A step down voltage converter is a 220 to 110 volts converter. A step up converter is a 110 volts to 220 volts converter. Our 2-way converters are voltage transformers that convert power from both 220 to 110 volts and 110 to 220 volts. They also work with 100 volts, 110 volts, 120 volts, 220 volts and 240 volts. This model is a 2 way voltage converter / voltage transformer available in many different sizes including 100 watts, 200 watts, 300 watts, 500 watts, 750 watts, 1000 watts, 1500 watts, 2000 watts, 3000 watts and 5000 watts.

Yes, the adapter takes 120 volts... Best way might be to get a 220 to 110 trnasformer converter then you can run other stuff as well... Get one of the step down transformers in first column... the 100 watt one would be more than adequate, but for future things you might want higher rating.

What voltage is your mains supply?
The laptop's adapter should be a multi-voltage type 110 to 240 volts input.
If your mains is 110 volts AC then the 220 volt AC LCD projector won't work unless you connect it to a step up transformer (110 to 220 volt transformer).
If your mains supply is 220 or 240 volts then both the laptop and the LCD projector will work without any problems.

It sounds like the replacement 220 volt transformer is putting out too much power, as replacing a 110 volt transformer with a 220 volt one should have no effect on other components, as the output voltage and amperage should be the same as the original one.

Find the breaker for it (a double for 220) and substitue a single breaker (for 110). This will leave one wire unused from the breaker box to the outlet. You'll have to change the outlet of course to accommodate a normal 110 plug. You can also skip the breaker part and just change the outlet and cap off 1 of the hot wires. Just make sure to kill the power and be safe!

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

Hi

check all semiconductor in the power board and look for a shorted and open parts! then replaced the defective parts.

Thanks!

Well, as a rule for electronics:
The United States and Canada use 110-volt electricity.
Most countries outside North America use 220-volt electricity.
Unless your appliance is dual voltage, you need to use a "converter" or a "transformer" to change the 220-volt electricity into 110-volt electricity in order to use a 110-volt appliance.
If your appliance is dual voltage, you can switch it to work on 220-volts, without a transformer or converter.

HOWEVER

Desktop units have a selector switch for 110 / 220 volts., which is done away with in the case of laptop one's which sense the input voltage and regulate accordingly.

I think your main concern is just that you have an adapter for the plug to go into the wall outlet.

Hope that helps :)
