Get a 120VAC to 240VAC step up transformer.

 

Hi,
Purchase a 1:2 step up transformer of a suitable wattage rating.

I have no 220v outlets I my house. I have a few audio projects that require 220v. How can I achieve getting 220v.

If in N.A. then the respective voltages will be 240v & 120v Typically.

 

Note that the transformer can't deliver more power than the 120Vac outlet, which is typically about 1500W in the USA.

Well option A would be to purchase a step up transformer rated for the power you want or need. As your power demand increases the price will follow. There are also step up converters. A simple Google of "120 volt to 220 volt step up transformer" should get you results for both. Just make sure if you use a converter type device or inverter type that you have a TSW (True Sine Wave) output unless you can do with other wave shapes.

Option B is most N. American residential power delivery is 240 VAC 60 Hz so if you can live with 240 VAC 60 Hz it's available. Just a matter of running a line from the entry circuit breaker panel to where you want it. Wire gauge and insulation to be determi9ned by how much power you want or need.

Finally there are rules.

Need to work in the rules.

Many folks suggest using a step-up transformer.. None of them asked for the power or the required current rating, although many suggested being adequate for the requirements.
My first question would be how much current does the device require??
Consider that in most residences the mains supply is 220 or 240 volts, split into two 120 volt branches. Adding a 220 volt outlet is not so terribly complex. but certainly it requires an understanding of what is involved.

 

projects? like DIY circuits (amplifiers)? none of them require AC, all audio equipment is ultimately powered by DC.
my question would be what DC voltage is derived from 220VAC. just get proper supply that produces that from 110VAC

I have a power filter board that requires 220vac input

 

I have a power filter board that requires 220vac input

 

The attachment shows a POWER SUPPLY module feeding an amplifier module. A "power filter" is not likely to need a specific supply voltage. The power supply shown is a switching mode supply and it may deliver adequate performance even with the lower supply voltage.
One very confusing thing is that the attachment shows the mains power supplied to both the power supply module and the audio amplifier module. THAT does not make sense as I see it. In fact, the more closely I examine that image, the less sense it makes. Is the TS able to provide us with the markings of the terminals on those modules?? And any possible link to the on-line descriptions?

The problem with Chinese origin equipment (AliExpress) there is usually a lack of technical manuals or info.

What do you mean by "a few audio projects that require 220v"?
Give us specific details.

It's a 12v aux for the fan

That makes no sense to me.
Ignore the filter board for now.
What are the power requirements of your audio electronics?

+-70vdc. I have a transformer rectifier etc to get that already. I want to use that board and I have the need for 240 for other things also

You don't need 240VAC.

 

You don't need 240VAC.

The board requires 240ac input and gives +-65vdc and 12vdc output. So what your saying is I could just use 120vac input

That is not what I am saying.
We have been given no data on the board so we don't know what the board does.
Without that information I say get rid of the board.
You are saying that your audio equipment needs +/- 65VDC and +12VDC. Then give it that.
240VAC is a red herring.

If it is a 12 volt feed for the fan the why does the picture say AC 220v??With a description like that, I WOULD NOT BUY IT EVEN IN A STORE WHERE I KNEW FOR CERTAIN THAT THEY WERE HONEST.
That description drawing does not match the words, not even close.
