Can you?


Can you tie 2 12 volt transformers together? My concern is the load coming back. Tell me what you think, thanks.

With proper phasing,

in parallel, identical 'formers, yes.
Non-identical 12 v 'formers in parallel, probably yes by adding a current-sharing resistor.

For a series config. the current drawn should be less than or equal to the rating of the smaller one. The output voltage does not have to be the same, but I can tell you that if you put a 30 kv neon sign 'former in series with a 7.5 kv unit in order to get an even bigger arc, the insulation in the 7.5 kv unit will soon fail.

Have one 2 hundred and one 6 hundred watt, having an issue with voltage drop. Would like to tie them together to solve the problem. They are mounted inside and exit through weather proof box outside. The lights were installed pryer to my involement. I was wondering if I tie the 2 hots together outside will it or will it not become 24 volt, and if that is the case will the load coming back burn up the transfomers?

1 What issue, exactly?
2 Depending on the phasing you will get 24 vac or 0 vac.
3 What do you mean?
