I have 4 solenoid valves being controlled with a raspberry pi and relay board setup.
They are 12V DC, but I accidentally ran them on a 12V AC power supply. I noticed they were getting hot and buzzing.
It was after looking closer I realised my mistake.
I replaced the power supply with a 12V DC one. The buzzing went away, and I thought this would also fix the getting hot issue.
However it didn't. They are getting hotter than before, so hot that I can not touch them.
Is it normal for solenoid valves to get this hot? If not, does anyone know what I can look at to try and fix it?
