Hi I am constructing a project that uses an arduino to turn on and off 3 high voltage power supplies (12v to 20000v) with a 5v relay shield. These are connected to metal plates that create a spark and it makes a kind of beat or music composition using the sound of the discharge. Everything is working great however, these power supplies keep failing? I have had three die on me and I cant figure out why? They work and then all of the sudden stop and start to get really hot. The only thing I can think of is that- A. They are not meant to be turned on and off regularly or - B. I am using 9v instead of the recommended 12v because the output was too strong with 12v. Can you think of anything else?
Please help! I need this to work in a few days. Thanks!! Here is a link to the generators I have:
