Voltz New Member May 3, 2010 #1 Title says it all, I need a 240-36V Transformer but I can't find one, maplins has 240-18V Transformer, how do I connect them up to give a 36V Output Thanks in advance

The CT is the junction of the two secondary windings. Do you have a picture of the transformer to post.??

Hero999 Banned May 3, 2010 #3 They have twin secondaries which can be connected in series to give you 36V, so you only need one transformer. **broken link removed** What VA rating do you need? Are you aware that the rectified voltage across a capacitor connected to a 36V transformer will be 50V? There are better places to buy transformers than Maplin you know.
