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...|||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.|||Sounds right.|||It's not obvious because we don't know how the first two are wired up.
In theory it appears to be sound though.|||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.
