Re: (Beginner) Varistor or TVS

Thanks for you advice Chris. There were a few problems that had me
started with this project too late which i won't elaborate further.

If i follow your method, won't i have 2 plug heads (don't know what's
the proper term)? 1 plug brings in the signal to the transformer the
other brings in the power supply from the wall wart?

I have already ordered Bel's powerline signal coupler, can i try and
build it like the schematic drawn in the data***? The live and
neutral wires are connected parallelly to the coupler and the PSU
(step-down transformer). Since the coupler only passess the Homeplug
frequency of 4Mhz-20Mhz filtering out the 50/60Hz power freqeuncy i
should be safe right? For the step-down transformer i'm thinking of
using any encapsulated PCB transformer available on Farnell.

Please advice.
