Any particular reason you need an enclosure for it?

I've got a KB VFD and was going to put in an enclosure.
It sounds similiar to your DC controller. It has a big heat
sink in the back. The wiring goes through knock outs, so there are
no exposed connections. Mine is mounted on the wall so
under a cabinet so nothing can fall into it. I mounted a
piece of plexiglass on the wall and cabinet at an angle
so the lathe can't throw anything at it. That save me
from having to buy the remote panel kit. Of course if
yours have exposed connections it will need an enclosure.

I lucked up and found a source for KB Electronic DC controllers
locally that will sell to me wholesale. I had been going to buy one
controller in particular, that was already in an enclosure, but he
explained to me that I would be ahead in the long run buying another
model with the factory installed heatsink etc already on it, as it was
better than the ones yu could add a heat sink to as the components in
the chassis type had the items needing cooling already attached to the
heat sink, instead of just placing a heat sink against the enclosure
box itself.

So I bought the chassis type, but need to make a box for it. I plan on
making the box out of acrylic plastic, with the back of the box cutout
to allow heat sink to extend throuh outside of the box for cooling. Do
you think it would be a good idea to add perhaps a 1 1/2" muffin fan
or even a 3" muffin type fan to this acrylic box to pull air over the
internals that the box is now enclosing and duct it oput down and over
the heat sink? Or should I be able to just enclose the chassis and
have the heat sink exposed to ambient air for cooling? I do need to
enclose it as its going to be mounted in the lower section of my 20"
bandsaws base cabinet, which does get dust etc in it. I plan on
relocating the speed pot to the front of the saw for easy access just
like my old controller had..... HOw much space should I leave around
the chassis for air flow etc? I am driving a 1.5hp 107VAC 15 amp DC
motor.

Any suggestions appreciated.
