How to replace 2 electrical transformers with one?

I have 2 electrical transformers at 12volt, 500mah. If i want to replace the 2 transformers with one, would it need to have an output of 12volts 1000mah (1 amp)? It just seems to obvious...

1. Sounds right.


2. It's not obvious because we don't know how the first two are wired up.

   In theory it appears to be sound though.



3. No is the transformer is asking for 500MA you can't use one with 1000MA, your exceeding the amps in the circuit. You will have to modified the circuit or wire it in parallel to ac hive the amperage. Or you could get a transformer with a 12 volt pri-sec windings. hope this help.


4. You are right that you would be safe as to

   the load, to just add the ratings.

   Just do be sure that those two transformers are

   connected to the same circuit and controler

   on the line side. Then split the load and reconnect

   the wiring as before.

   At the sizes you are dealing with, wire sizes are

   not a factor, and unless you're dealing with VERY

   sensitive electronics, neither is current limitation.
