NCDX heatsink..

[Richard Ellis]

I'm curious about this Class 'D' module.....how, and or where is there a heatsink...applied to this module???
And just how are these D mods?
These guys have this package deal but there are two different values for B+/-................A 42V & a 40 VDC...........40-0-40 or a 42-0-42.
Antek makes a 42-0-42, but not a high enough current.but the 40-0-40..I would go for the 1000W version...to be conservative. Couldn't one run a ribbon cable to a chassis faceplate as the module will be horizontal?......for the diagnostic display...

thoughts???????

isnt that the heatsink on the underside?

class D doesnt need much heatsinking. Just look at the peavy IPR series which runs at 2k without a sink :O

The aluminum block visible on the underside is meant to be either connected to a larger heatsink or connected to the chassis acting as a heatsink. I don't think the block itself can dissipate all the heat generated at full output power.

That block is definitely just an interface part to make heatsinking easier. It's just a conductor, not a sink. Whatever you do should probably not allow that block to get warmer than say 50C.

[Andrew Eckhardt]

Since it is entirely likely that someone might try to stick that onto something like a thin piece of sheet, it also sets up a sizeable minimum thermal mass, which minimizes thermal shock.

also you don't really need displays... have open case for few day to get over it, or put plexiglass or something for top side
