Yeah, that should do it as long as you don't plan to add a second solenoid (2 guns).
But if you want my advice, I would take a look at "aliexpress". You can buy a power supply with higher amperage for much less (I did buy mine there and it works flawlessly).
Sounds great but would you be able to give me a couple of examples?
I don't think I'll add a 2nd gun but you never know, I guess.
I'm lost as to which number can go higher. Is it OK to go for a PSU that goes beyond 5 amps? Is it OK to get one beyond 36 volts? I don't know which one would be acceptable to go beyond the recommended range.
How many amps and volts would I need to get a 2-gun setup?
Lastly, how could I wire it so both work?
Sorry for the many questions, but again, I'm a newbie and am trying to educate myself about this. There's unfortunately not a lot of easily found info about my specific questions out there.
