SSL9K PSU question

[jrmintz]

Hi all,

Will this variant of the SSL 9k power supply work? Are there any problems with this?

Thanks everyone.

I think you'll need more than 24V in to get 48V out... at least 36 or 40V RMS...

If you're doing it that way, because the OV will be referenced together, there really isn't much call for 2 bridge rectifiers anyhow...

This probably isn't the best appltication, someting more akin to a true voltage doubler would work... essentially another diode/cap stage in the 48 multiplier/shifter.

Thanks, Keef. I was just wondering.

I think there;s one at Rollmusic which will do what you want... simpler, too! (If I'm not imagining it...)

Can the ssl psu be run from a wall wart?

There's also this one:

although the 48V-section could use a ground-connection :wink:

Haven't build this, but it looks good.

...but wait, the schematic at the beginning of this thread has this one missing as well - am I missing something ?
Hmm no, that 48V-section needs a ground-reference as well, right ?
