40v transformer

Hi i'm currently on a project about measuring power consumption and communicating the data via the power line.

I have decided to use TDA5051 for its ease and simplicity to build.

However, I have a restriction on testing this over 240V line due to safety reasons and will need to be reduced to 30V. Are there any transformer which can transform 30V to 5V?

Thanks.
 

30v to 5v

It's just the ratio that you need worry about.
30/5 = 6,
240/6 = 40.
So a mains trans former such as a 240 to 20-0-20 will do the job.
