Economy Japanese Step Down Transformer – The Economy Japanese Step Down transformers can operate your Japanese 100 Volts rated appliance on the Australian 240 Volts power mains supply. Our Tortech Economy transformers include a fuse and thermal cut-out protection to ensure the transformer cannot be overloaded. Our other transformer type of the Isolated transformer model includes these protection features and also additional features including voltage spike protection and can help assist noise filters (see here for Isolated version). This model is a single wound toroidal transformer, and is designed to only convert the voltage from 240 Volts Australian mains supply down to 100 Volts Japanese rating, thus allowing your Japanese device to run in Australia. Simply plug your transformer into the Aussie power wall outlet and then connect your Japanese device into the power socket on the unit. Once they are both connected, switch the power on at the wall socket and for the step down unit, and you’re ready to go! Protect your Japanese appliance – Buy a Step Down that is guaranteed safe: Important note: Why you should not use a USA stepdown for Japanese appliances: Contrary to advice from others – running your Japanese device on a USA rated stepdown transformer will eventually destroy your Japanese device! Most Japanese equipment runs at 100v and by using Japanese appliance on a 110/120v you will encounter overvoltage. This overvoltage can deteriorate your appliance until it will stop functioning correctly. Additional FAQs about the frequency difference & more technical information, please read here.
