[ISOLATED] American Step Down Transformer
Isolated American Step Down Transformer – Isolation American Step Down transformers are essential for safely running your American 110/120 Volts rated appliance in Australia on the Australian 240 Volts power mains supply with additional protection and filtering features.
Our Tortech Isolated transformers include additional features detailed below which are not offered by our Economy model transformer (see here for Economy version).
This model is fully isolated (insulated input to output) through a double wound design and is the only model that provides additional protection for your appliance against voltage spikes in the power supply, as well as helping filter the audio quality for amplifier type equipment.
Note: This model does not include an Earth Screen. If you want to have an Earth Screen included, Tortech can manufacture a custom unit by specifying your design requirements here.

This unit uses a toroidal transformer to convert the 240 Volts Australian mains supply down to 110/120 Volts American rating, thus allowing your USA device to run in Australia.
Simply plug your transformer into the Aussie power wall socket, and then connect your American device into the USA power outlet on the unit. Once they are both connected, switch the power on at the wall socket and at the step down unit, and you’re ready to go!

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.
