 | | 13V ~ port on 12V transformer —Simon Denscombe
|
| | | My question is what is it for? My dad says it is the first change after the step-down from 240V (Europeans who use 220V transformers have a 12V ac port). The other 2 ports on the tranformer have a use - one for accessories, one for control of the (...) (25 years ago, 22-Aug-99, to lugnet.trains)

| | | | This means, that now when we have 230V in Europe (European Union standard as it is between 220 and 240V and whitin the limits), that it will be app 5% more ~almost 14V. I have never checkid it, but the 741 (740, 742) is only a transformer basically (...) (25 years ago, 23-Aug-99, to lugnet.trains)

| | | | (...) Well we are still running at 240V (officially 230V) using the 15% upper limit. (...) Possibly, the transformer to get from 230V to 13V and the diodes for the rectification for DC. (25 years ago, 23-Aug-99, to lugnet.trains)
