Voltage Converter 220 to 110 Step Down Transformer 500W Adapter , No Noise , Ten Protection Functions , CE & CQC Certified

Does this converts 50hz to 60hz as well?

I have a european (italian) appliance that is 220-240v rated, 50hz, 1.7amps, and .33kw....is the 2000w step-up converter sufficient?

220v 50Hz, or 60Hz ?

Any chance this is a pure sin wave?
