Can anybody see any potential problems with swapping out AC-to-AC transformers? I am considering using a transformer that is used by a security camera system, on a sprinkler system. In addition to powering the timer electronics, the power is used to open the sprinkler valves. The voltages match up, and the new transformer has a greater current output (830mA) than the old one (650mA).
With DC power supplies, switching can cause noise and interference. Is there any scenario in which the new AC transformer might be of a different type and cause problems? For example the new transformer was made to power electronics instead of mechanical actuators so pulsing might be an issue, or perhaps there are different AC transformer types that should not be swapped. Is the E-I type the only ones found in a wall-wart, or are there other types of small AC-AC transformers? (Toroidals aren't used in wall-warts and there isn't an AC-AC equivalent of switching is there?) Basically, I'm wondering what variables exist between transformers besides voltage and current output.
