RE: Slaved power control 'current transformer'

["Steve Morgan" <smorgo@xxxxxxxxxxxxx>]

RS Components have loads of current transformers starting at a few
pence.
They also have current sensing relays that you can connect a current
transformer to but they're rather more expensive.

That's the principle, Chris, except it can only go round one wire of the
tw=
o

and needs 100s of turns ('current transformer') then amplification etc.
I=20
can build it, but surely someone has one as a pre-built module for around

fiver? Closest so far is about =A312.50 for an 'Intelliplug' then rip its
