Default UcD180 modules placement

hello all,

I'd like some input in what would be the best way to orientate my UcD180 modules in the case.

They'd have to be in sideways so I can reach the jumpers I have attached to short the input caps.

I've got it boiled down to 2 options.

The first I like best because the output coil of both amps are not directed towards the input. Slight worry about the one coil not being able to radiate its warmth freely (obstructed a bit by heatsink; but still in relative free air)

Default Second option

The other option has both coils on top (better cooling), but looks less nice (I think) plus I'm a bit worried about the proximity of the coil to the input chassis.

Thanks in advance for your thoughts.

Johan

To me, first option looks fine, I did the same in mine (see attached picture). The coil doesn't heat up that much that it would need a good dissipation.

- cheers

Thanks both for your input.

The score is now 1-1.

Dan, can you give me an estimate on how warm the coils get?

Thanks again,
cheers,
Johan

I never measured it, but it gets not more than handwarm, even not hot. Depends if you party with it or not, but even you'd heat it up extensively, no harm would occur. In fact, after saturation because of the heat, the coil will "see" the winding without the ferrite (because of the saturation, the ferrite would be virtually absent), and thus it change its value. Sound would change, but as I said it is nearly impossible to go that far.

Thanks Dan,

I rarely party with my amps, so effectively no reason not to go for option no. 1

Cheers,
Johan
