What should i use to convert 230 VAc power to 110 VAc?

Question

Iincoming supply is 110 VAC and components fitted in the Appliance run on 230 VAC I need something convert

Answer 1

You can't go in that direction. If the Appliance was 110 VAC and the Line was 230 VAC, then you could (possibly) use a convertor to drop the voltage. But to go from 110VAC to 230VAC, at any current at all (It is possible, but it's expensive) then you would be better to just throw the appliance away and buy something similar in the U.S.

Besides the voltage difference, your appliance probably is designed to run on 50 Hz rather than 60 Hz and that can also cause heating problems.

My advice... dump the appliance and get something that will work on U.S. Power.

Answer 2

Either a transformer or a electronic voltage converter. Depends on the power of the appliance you want to run. If it needs a lot of power and you only intend to use the converter to power this, you could be better buying a new appliance at the correct voltage. An auto transformer will be the cheapest solution probably, but remember an autotransformer doesn't isolate the appliance. These will often be used with power tools and the same one can convert either way, from 110v ac to 240v ac appliances or from 240v ac to power 110v ac appliances. Electronic converters will only work one way usually.

Despite what the previous answer says, if it's an electronic device the 50-60hz almost certainly won't make any difference. TVs and computers etc. merely swap the voltage, the ac hz doesn't matter as it's all converted to dc anyway. If it's electrical it won't make much difference unless it uses a synchronous motor. Here in the UK we use autotransformers on tools all the time to run power tool on sites at 110v either because of safety or because we want a particular brand of US voltage tool.

Check to see the appliance doesn't have a voltage converter somewhere in it. If necessary, contact the manufacturer.

Answer 3

Check first your local electricity, if your line is 110-110 or 220-ground

For 110volts incandescent bulbs, you can use a diode on one line so it will block the AC current and you will get a 110volts DC (applicable only for 110-110 line)

But for items with transformers (non critical), check the power consumption and purchase a transformer that can carry the load, a 10% allowance is advisable so it will not heat up so much for prolong use.

AVR is good for sensetive items (computers, lab equipments) it monitors and filters the line before the power reach your appliance.

Answer 4

Just buy the right AVR voltage on it.

Answer 5

by using step down transformer of230\110vac
