Step-down

Step down transformer is the ideal solution if you have an appliance designed to run on America's 110/120v or Japan's 100v power but is needed to run here on Australia's 240 volt power. The transformer is essentially a voltage converter.

 

We offer different step down transformers based on country and voltage - select the from range below:

 For Household American devices 110 - 120v we recommend our economy step down transformers see here

 For Commercial American devices 110 - 120v or high value items we recommend our Isolated USA stepdowns here

 For European 220v and Asian devices on 220V step down transformers see here

 For Japanese 100v devices our Japanese step down transformers see here

 To run a Australian Device in the USA see our step up transformers

 For 3 phase step downs see here.

 

 Important difference - Not all step down transformer are made the same:

Tortech step downs are designed to run continuously 24/7 as the internal transformer is toroidal (round).  

This means the amount of power available - the rating, does not drop after 40 mins of use! Read more.

    - The Tortech difference is the power saving, high efficiency toroidal transformer inside


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

      1. A safety Fuse for short circuit Protection.

      2. Thermal overload protection in the winding of the transformer

    2400 Watt Step Down transformer      Part No. Sd110-2400A

    For USA devices 2400 watts or less. Max 21.8 Amps  16Kg

    Why we have no 3000w stepdown in economy range? A: Normal power in most Aussie homes has a limit of 10 amps 10 x 240v = 2400w .

    You can not supply 3000w from a normal 10amp Aussie household outlet . You will need to check that you have 15amp Aussie power outlet which most residental homes don't have. 

    Therefore, for most homes the 2400w stepdown will supply the maximum power available.

    Important Qn: Why are these Hard Wired? (ie no output US sockets)

    At 3500w the output current is 32 Amps. The standard USA UL approved 3 pin socket is limited to 15 amp. 15 x 110 - 1650 watts. This is the maximum power you can extract from one USA standard output socket. Therefore other stepdowns that show 2 x 15amp sockets have a transformer that simply can not deliver the promised output power.
