Bought some of the ac to Dc modules. Can you hot glue these to a surface and what do you do to protect against abuse?

Nor sure what modules you have, or what type of abuse but here goes....
Hot glue on the corners of a circuit board will work. Most electronic, and some hardware stores carry "stand offs". They are snap in, or threaded hex. legs, of different lengths between 1/8"-2". A small threaded male on one end, female on the other end, stackable to layer boards. Metal and plastic standoffs are made.
If your mounting on metal, protect component legs tips with a sheet of cardboard cardstock behind the board is a good idea. An electronics shop can supply thin anti puncture, high heat, non-conductive plastic sheets to do the same job.
The add on command companies used double stick foam. Seems to work well. I think you can find it by 3M.
I use double-sided 3M foam tape, it's worked well in a lot of installations. If they're in close quarters, I also encase them in heat-shrink to keep them from shorting to anything.
