This may be of interest to some people. Having had a look at Magnelab CT's I requested a bit of further information, that isn't on the website, about some of their range and was quite surprised at the reply.

I asked what the coil ratios were and got the following reply:


UCT-0300-000 1:880

UCT-0500-000 1:360

UCT-0750-000 1:3000

UCT-1000-000 1:1000

UCT-1250-000 1:1200
