Step down Transformer – American Voltage Converter for Australia Order Above

A step down transformer is the ideal solution if you have an appliance designed to run on America’s 110/120 volt system but is needed to run here on Australia’s 240 volt power.

This transformer converts 240 volts down to 110/120 volts to allow your USA device to run in Australia.

Simply plug transformer into the Aussie power socket & the device into the US power outlet & your ready to go!  

Protect your USA appliance – buy a step down that is guaranteed safe:

  • Our transformers are made to the highest quality standards
  • All voltage converters come with a 1 Year Money Back Warranty
  • Designed to protect your device
  • Unlike others, our voltage converters are designed to run continuously 24/7- read why important
  • Quality casing & included Safety Fuse protection
  • This new range is lighter & more compact
  • Safety fuse protection (300W and above)
  • Strong Carry handle, Enclosed and strong metal construction rubber feet (300W and above)
  • Thermal overload in the winding of the transformer
  • Thermally tested to Australian Standard AS/NZS61558

These features ensure your USA device runs safely on Australian power.

Select from our Step downs transformers based on how many watts your device uses. 

Choose the transformer rated above your devices watts usage.

E.g: Playstation 3 uses 380 Watts so you need the 500 watt rated stepdown transformer.

If a motor is included then you should select a stepdown rating approx 25% higher than your motor as a buffer.  

Motors have a higher power use on the stepdowns and startup currents which need to be allowed for.

Most motors have a rating plate on them with their Power and Amperage rating.

If so, how critical is this timing device?The Transformer cannot change the Frequency. It is 50Hz

If a timing device is included the speed of the device may change due to the frequency change, 60Hz to 50Hz (eg old clocks, motors / fans/microwaves ) Most modern electronic devices should not be affected. Read more about frequency

Calculated as Watts = Amps x 110Volts  (eg 5 A x 110 V = 550 watts)

Check total watts of all devices this must be less than the VA (Watt) rating of the stepdown & get a US Powerboard. 

Frequently asked Questions about the frequency difference, 110v, & more read here
