I have a power supply that says it is 24VAC output, but in reality is is giving a steady 29VAC of output. Is this normal? I am powering sprinkler solenoids that say 24VAC. So my question is how can I drop the voltage so I can supply 24VAC. I found some buck converters, but they seem to be DC only or AC input and output DC. I am assuming resistors might work, but an unsure of how to calculate for AC, and wondering if there is maybe a specific device that is made for this purpose?
I have done some work in DC, but AC is kinda new territory, so any help/explaination is much appreciated!
