Try at a electrical wholesale outlet. Don't know why you would want a auto transformer. A standard 240 to 120 transformer usually does the job and it can be run backwards or forwards. 240 primary 120 output on secondary or 120 primary 240 output on secondary. Either way you will have to know the amperage of the load to get the correct size of transformer.

You can buy an auto transformer with 0-120-240 volt output at electrical supply stores, online retailers such as Amazon or eBay, or specialty electronics stores. Make sure to verify that the transformer meets your specific voltage and power requirements before purchasing.

Can you use 240 volts with a 120 volt supply?
No, it is not possible to use 240 volts with a 120 volt supply directly. You would need a transformer to step up the voltage from 120 volts to 240 volts. Attempting to use 240 volts with a 120 volt supply without a transformer can damage equipment and pose a safety hazard.
How do you convert your 110 volt neon sign to run off 240 volt UK socket?
What you will need is a 240 to 120 step down transformer. An adapter might work but it depends on what the current draw of the neon sign is at 120 volts.
How do you change a 220 240 volt wire to a 110 120 volt wire?
To change a wire from 220-240 volts to 110-120 volts, you will need to reconfigure the wiring by connecting it to a transformer that steps down the voltage. This transformer will reduce the voltage from the higher range to the desired lower range, allowing you to safely use it with 110-120 volt systems. It's important to ensure the transformer is compatible with the current and wattage requirements of your device or equipment.
How do you get 240 volts out of a 110 outlet?
You cannot get 240 volts from a 110-volt outlet without using a transformer or having a dedicated 240-volt outlet installed. It is not safe or recommended to modify the outlet to achieve this.
Do you need a step down transformer to run a 208 volt steam table on 240 volt feed?
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
How can you get a 240V single-phase power from a 120V 3-phase service?
First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.
How do you convert your 110 volt neon sign to run off 240 volt UK socket?
What you will need is a 240 to 120 step down transformer. An adapter might work but it depends on what the current draw of the neon sign is at 120 volts.
Where are center tapped transformers used?
The transformer that feeds your house is a center tapped transformer. Primary 7200, Secondary 240. The 240 volt secondary is center tapped to give you 120 volts on either side of the tap. Hence house voltage is 120 / 240 volts.
Can you use 240 volts with a 120 volt supply?
No, it is not possible to use 240 volts with a 120 volt supply directly. You would need a transformer to step up the voltage from 120 volts to 240 volts. Attempting to use 240 volts with a 120 volt supply without a transformer can damage equipment and pose a safety hazard.
Can you sub a 240 volt 1.5 amp transformer in place of a 240 volt 3 amp transformer?
If the load you are connecting to the transformer uses 1.5 amps or less, yes.
How do you convert 230 volts to 12 volt system?
With a Step Down transformer. But you will probably have a hard time finding a 240 volt unit. 120 volts units are readily available. <<>> It depends on how big of a transformer that you are looking for. There are many control transformers in the 50 to 500 VA range that have dual primary and dual secondary. The primary side can be connected to 240 volt or 120 volt and the secondary can be connected for either 12 or 24 volts.
What is more efficient to run a pool pump on 120 Volt or 240 Volt?
240
Is there adapters for 250 volt to 120 volts?
No. There are no "adaptors". To get 240V from a 120v supply you use a 120-240V step up transformer. <><><> Clothes dryers, water heaters and and other high-power 240 volt appliances cannot be run on a transformer from a 120 volt circuit. They must be powered from a separate branch circuit that has the right size breakers, cable and socket outlet to suit the appliance.
Does a transformer convert the current from 240 volts to 120 volt?
Transformers are rated in KVA or VA (volt-amps). They transform voltages from one value to another. The current in a transformer is inverse to the voltage. This is why transformers are rated in KVA and smaller ones in VA.
How do you size a transformer based on amperage I have a 1 KVA single phase transformer I was told I can only put 4 amps across the secondary. This transformer is 240 volt primary 120 volt secondary?
On a 1kva you have 1000 watts capacity. To fine the current the formula is I = W/E. The secondary side of the transformer has the capacity of 1000/120 = 8.3 amps. In your question you do not put the amps across the secondary you draw amps from it. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. <<>> voltage times amps equals wattage
Does a 6 amp 240 volt appliance hook up to 110?
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?
A single phase 600 to 240 Volt transformer using two phases of the three phase primary.
