Since it's an industrial PSU I had to do a little wiring to get it up and running.
But since I'm currently here blogging about it, I guess it went well...
The neat thing is that I can adjust the voltage +-5 volts, which can be used to limit or increase flipper strength. That and built in overload protection and current limiting should come in handy!
Oh, and I found out that the same company that I bought the PSU from also sells the MOSFET I wrote about earlier... But they cost 0.8$ each! Just ordered a bunch!
Man, I love internet!
