[ECONOMY] American Step Up Transformer


USA to Australian Voltage Converter – Run your Aussie Equipment in America!

A “Step up” Transformer is the ideal solution if you want to run an Australian appliance designed for 240 Volts on American Power at 110V or any other Voltage.

This transformer converts 110 Volts into 240 Volts to allow your AUSTRALIAN appliance to work Overseas in the USA, or a Local 110V supply.

We can also build converters to Order, for other Countries and Voltages.  Please Enquire Direct.

Simply plug the transformer into the Power socket & your device into the AUST power outlet & you’re ready to go!

Service is Important.
We Offer Quality Service.

At TorTech, we encourage all of customers to come visit our office in Greenacre, Sydney for assistance in selecting the right voltage converter for you! Our team of specialised engineers are happy to examine your product and assist in helping pair you with our recommended voltage converter out of a wide range of stock.

If we don’t have a voltage converter in-stock that you require, we can manufacture you a custom transformer that will meet your needs! If you are experiencing any difficulties with our transformers with your product, we can help resolve the issue by testing both the transformer and product at TorTech. We aim to ensure you are satisfied with your decision and continue running your appliance without any problems.

Note: in the USA input power max is 15 amps This means 15 x 120v = This means maximum power of about 1800 watts is available.

If you are unsure about what step up you will need please check these questions:

When decided on which Transformer will be suitable for your appliance/s, it is important to consider the Power Rating of the device/s you wish to run on the Transformer.

To determine the Power Rating of your appliance/s, you must determine the total wattage (W) or total ampere (A). This will be presented on the product in a electrical specification label, or in the product manual.

Once the total wattage (W) or total ampere (A) is determined, please use our ‘Calculator’ located on the tab section of this page. This calculator will help guide you on which Transformer is recommended using your appliance/s details.

Always note that the Transformer must always be 20-25% higher in wattage (W) rating than the total wattage of your appliance/s.

E.g: Playstation 3 uses 380 Watts, so you will need the 500 watt rated Step Down transformer.

If a motor is included in your appliance/s, then you should select a Step Down Transformer rating approx 25% higher than your motor as a buffer.  

Motors have a higher power demand on the Step Down Transformer and draw higher start-up currents which need to be allowed for.

Most motors have a rating plate on them with their power (VA), wattage (W) and/or ampere (A) rating.

If so, how critical is this timing device? Our Transformers convert the voltage (V) and cannot change the frequency (Hz). 

Please note Australia’s power grid supply operates at 50Hz. 

If a timing device is included, the speed of the device may change due to the frequency difference in the power grid. This results in the appliance/s operating at 50Hz (Australia) when designed for 60HZ (Western Japan). An example of which appliance/s may be more affected by this are: old clocks, motors/fans/microwaves.

 Most modern electronic devices should not be affected. Please read further about frequency for more information.

Calculation for Wattage:

Wattage (W) = Ampere (A) x Voltage (V)

An Example is Wattage = 5 Amps x 110 Volts = 550 Watts

Please check the total watts (W or VA) of all devices and ensure this is 20% lower than the power rating (W or VA) of the Step Down Transformer. If using more than two devices, please use a USA Powerboard to run multiples devices. 

If still unsure please contact us to work out which step up transformer you will need.
