If its an electronic transformer, it might not be mains frequency. What do you want to do with it ?

That won't work as a flyback driver without more electronics.

check the output waveform, it's a high frequency which can drive a flyback.

If it's 50Hz or 60Hz going in then it will be 50Hz or 60Hz coming out.

no, because smpsu's use pulse-width modulation,and therefore output a high frequency, instead of a normal transformer, in which the output frequency is the same as the input frequency.

I ripped one of those apart, definatly an switch mode power supply-so it'll work for your flyback driver.
