A COMMON QUESTION “WE NOTICE YOUR TRANSFORMERS SAY 110V AND OUR ENQUIMENT IS RATED AT 120V WILL IT STILL WORK?”

Answer – Yes All our Transformers support USA equipment 110v-120v
Our stepdowns run at 110v because of the numerous safety advantages for your USA equipment:

  1. The supply of power and it’s  voltage in Australia is 240v +/-6%. This means aussie power can vary above or below 240v.
    So it can legally vary up to 255v at 50Hz.
    The transformer is a linear device so the output voltage responds to the change in the input voltage. This a means the  output voltage (110v) will go to 116.8v if the transformer is loaded.
    By running at a slightly lower voltage this indirectly reduces the change of input voltage fluctuations.

  2. If it is lightly loaded this voltage will go even higher to 124V . If we used 120v as the transformer output voltage, the appliance could be overvoltaged to  134v
    This is may not good be for the longevity  of the appliance.
    If the appliance is a motor, the matter is it subject to the affect of frequency change from 60Hz(USA frequency) to 50Hz(Australian frequency).
    To alleviate the frequency affect it helpful to reduce the voltage from 120v to 110v, to reduce the induction level in the motor. The magnetics of the motor will then not run as hot as it would if it was run at 120v

If your transformer has stopped working it might be due to a blown fuse. All of our transformers are supplied with two replacement fuses, if you’d like to view our how-to guide on replacing the fuse, please click here.

Please note our website will only allow shipping within Australia, NZ and select asia pacific countries.
The significant weight of transformers means these items incur high international shipping costs and customs charges.

International orders over $500 AUD – Note: We do not organise, pay for or take responsibility for shipping to overseas customers for orders over $500. Payment for overseas orders must be made by wired deposit, we do not accept credit cards for international payments over $500.

All arrangements must be made by the customer with regards to overseas freight and no liability is applied to Tortech L/P in the event that the item goes missing in transit internationally. International customers must have their own established account with one of these three reputable shipping companies : UPS / DHL / FedEx.

The validity of these accounts will be checked with the relevant freight companies. We do not accept shipping via other less reputable freight companies.

Shipping to overseas is reviewed on a case by case basis.  Please enquire here if you have an overseas order.

Tortech Pty Ltd cannot be held responsible for products damaged by transit, fire, storm, water or other components or parts not supplied by Tortech LP or any condition not caused by the product’s operation.
