I purchased a Power Bright VC1500W Step-Down/Up Transformer before moving to Australia. I was under the impression that Australian voltage was supplied at 240V, but the standard was recently changed to 230V.
The back of the device allows you to select the input voltage (options are 110, 200, 220, 240):
Unfortunately 230V is not an option. What should I choose and will it be safe? What will the effective output voltage of that choice be? My family plans to use the transformer for US electrical appliances, including a blender, mixers, and a breast pump. Your help would be greatly appreciated.
