The transformer is ideal for converting 230 VAC mains voltage to 115 VAC. This is a real transformer with a sinusoidal waveform. In 220-240v countries, stepping down to 110-120v should work just fine. I am sure there is no risk of damaging my gear. I have the 500w model and it's good for devices that draw 1w to 400w total. It does have a 600 ohm resistor between primary and secondary ground, but this is good for preventing ground loops in audio and video equipment.
