You can safely use any ul approved device using 120v 50 ~ 60 hz if you stay within the limits of it's potential (in your case 2000 watt). You will probably have a loss of efficiency using a step up transformer and will be very limited on the wattage available at the 220v. Most converters are not designed for continuous use and recommend that you buy a converter with at least 25 % more capacity than you will use. Also to get longer life out of your generator, you should use only 75 percent of its capacity for continuous use. A 2000 watt converter will work fine for loads of about 1500 watts or less.

Howw do you make a Samsung bd-F5700 blue ray player operate on a 240 volt power supply


You'll need to bring the voltage down to 110-120 volt. Travel converters do this cheap and effective. The player only uses 12 Watt according to the manual. You could use an old 3 prong extension cord to cut of the connector to connect to your power supply. Get the converter below and plug it into the adapter, who then will fit in the extension cord.

Bought a singer from the state but cannot be used in australia what should i do?


If it is an electronic or computerized machine, you are out of luck. USA has 110 volt 60Hz current, Australia has 220 volt 50Hz. A transformer can change 220 to 110 volts, but it cannot change 60Hz to 50Hz.

I just bought KitchenAid Artisan Stand Mixer KSM150PS with 110v and 60Hz online and received it today and realised I cannot use it on australia. Can I use transformer which I can get here to convert 110V...


You need a Step Down Voltage Converter (also called a Voltage Transformer)
which steps down 240, 230, 220 volts to 110 volts and
allows you to use 110 volts Devices from USA in 220 v / 230 v / 240 v Countries

Is a dtxplorer bought in the USA set for 110 volts and therefore do you need to get a converter to use it in a 220/240 volt country?


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.

I have a customer that recently replaced his generator, problem is , he got a 120 VAC output. He has 2 SW 4024 for 240 VAC output. Can I hookup the 120VAC to the master inverter, or should I get a...


Hello,

I will accept the second option which is getting transformer.

Go ahead and get a transformer in order to step up the voltage. This is better than hooking up the 120V AC to the master inverter.

In summary, get a transformer to step up the voltage.

I hope this is clear now....

Good luck.

It came with a american plug and when we put a converter to australian plug on it it only shows 220w instead of 240 which is what we have in australia. Don't want to plug it in and it blow up on me.


I think you mean 220 volts, versus 220 watts. The difference between 220 & 240 volt equipment is usually just a matter of nomenclature -- no significant difference in terms of operating the equipment.

The vacuum is 110 / 120 volt since it has an "American" plug on it. If the plug is swapped for an "Australian" plug (or adapted) and plugged into the wall, the vacuum will be connected to 220 volts -- this would destroy the motor.

You would need a transformer to step down the Australian voltage to 110 / 120 volts. If you plug it in without a transformer, it will surely burn up the motor.

More info, let me know.

Will they work in Australia where we have 240 volts?


Yes if this UNIT has the specified mains voltage set for 240 volts then it must work in Australia.
If you have to bring up the voltage from a 120 volt supply then USE a STEP-UP transformer with a conversion factor of 120 volts in the primary to a 240 volt in the secondary.

I live in New Zealand which has 240 volt supply on the grid. The zantrex 2000 works with an input supply of 120 volts. How can I use it?


Hi, OK, there are two ways to achieve this. One. Using an external STEP DOWN Transformer, 240 V AC, to 120 V AC. The ONLY thing that matters is KVA. As long as the KVA is the same ir will work. This means as long as the Output Voltage and Current are the same, it's irrelevant whats on the Secondary. So if
The second, is to remove the existing transformer, and substitute with an exactly the same Secondary Outputs, BUT with a 240 V AC,. Input winding. Most likely it is a simple step Down transformer anyway, that steps down, whatever the external voltage is, down to say 12 -18 V AC. Therefor ANY suitable 240 V AC transformer with the SAME secondary winding(s) will work, no problems. You can even get some transformers Overwound, for 240 V AC, a very common thing, depending on transformer construction. There are a few transformer manufacturers in the "Yellow Pages" contact one of them and inquire.
As a tip, sometimes the existing transformer has TWO 120 V windings, and sometimes only ONE side is used, for US power, and for 240 V AC, you simply connect the other winding in series, and NOW you have got your 240 V AC to whatever.
