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.

Once ordered, the step down transformer was delivered really quickly only taking less than 2 days from order to receiving the item in Canberra. However, the item sent was the step down for Japan, and not North American. A quick telephone call and Tortech issued the postal return paperwork, and almost simultaneously sent the correct American step down, even before they received my returned step down for Japan.
While there was a small error in the process, the customer service in response to the error was great. Many thanks for your good, prompt customer service.

Isolated American Step Down Transformer combined with an Onkyo TX-RZ830 9.2 Channel 4K Network A/V Receiver.
I was advised that due to my 850 watt 110 volt 60 HZ ‘s Network A/V Receiver drawing more than 1000 watts than thought I got the 2000 Watt version.
I have been looking online for a while and buying an Onkyo TX-RZ830 9.2 Channel 4K Network A/V Receiver would cost me at least $2000-3000 Australian, so I took the risk and imported one from the USA. What a risk it was, but glad I did because I saved myself at least $1000. I actually got a brand new Onkyo TX-RZ830 9.2 Channel 4K Network A/V Receiver for $1000 Australian including delivery and import Tax.
Now all I needed was the Isolated step-down transformer and Tortech were happy to build one for me in 2 days and ship to me within 2 days. I grabbed the special $250 price that was reduced from $640!!
Happy days 🙂

Got a large Isolated stepdown 3500W unit to run my boat from shore power. Amen it works very well ! I previously had a another stepdown and I couldnt handle handle the load at all and konked out after 20 mins – this one can. I rely upon this one as it has to provide power to all appliances on the boat every time I move to shore power. This unit is built to last, to be honest its not light but well it’s made, strong handle. I eventually got a sparky to hardwire it in with a nema cable and store the whole transformer in the cabin with ventilation. Also being that it is isolated it gives me peace of mind that it is running safely in the cabin, as it runs all night and for days at a time when we are onshore. Thankyou for your help and assistance as well.
