new power supply, 100ma version angle bracket sicfet pass transistor coming

 

for the higher power applications.

Ha!

good for at least 100ma on each rail with enough heatsink

Now that will be a fun challenge to fit into the same box as two carbon boards. Definitely putting this into the project queue.

2 amp boards on one side, the power supply and transformer on the other side

Is this a better PS to use with a KGSSHV Carbon? I was planning using a KGBH/ST version.

I thought the original KGSSHV supply was good to 90ma with 3904s? Offboarding is a welcome addition though

Do the SiC MOSFETs need to be matched at all for either the PSU or the amp boards?

According to Birger, no matching of the SiCs required on the amps.

Maybe a good opportunity to change STTH512FB to STTH512FP, I just googled the first part again

 

Edit: Can the SiC also be jammed into the simpler BHSE supply?

its a to246, so it would have to be a different heatsink, and a different footprint

oh, I was thinking just leave it offboard and let the user handle sinking. Wondering what the dis/advantages are to the fq* part

n/m found one. thanks

@joamat:

 

- why did you change the servo?

- do you do your own Stax jacks? ...looks like that from your pic??

I just realized this, but how are you powering the LV section JoaMat? If you're using your T2 supply, I thought there was only 12V available

I use the T2 PSU sometimes and it has 12V LV section but it seems to work.

That's good to know, I have some 12V power ones that can get some use

Would it be bad to stack the two carbon amp boards on top of each other (perhaps slightly offset)? That would make it possible to use a smaller case than if they are placed side-by-side.

as long as the heatsink is big enough, that should be fine, and put the power supply on the other heatsink.

 

its still going to be a fairly big box

There are a number of case options with a single heatsink, I couldn't really figure out how do the IO for those in a tidy manner

I think that a build will fit in a Modushop Dissipante 2U 300 with stacked amp boards, but didn't actually lay it out to double-check. Not a small box, but not monstrous, either. A fully-custom chassis should allow more space saving.

are you planning to use the sic power supply?
