Power Supply

[Michael Jones]

Has anyone here ever built a 24 volt power supply with phantom power?
Any links or diagrams/instructions on how to do it?

Michael,

I suggest you visit the Tech Talk forum over at RO and post the question. They are a great bunch of people and usually someone will have an answer.

Add

to an existing 24v supply.

Here's a kit: you could also build it on your own from the schematic

goto PS01 power supply.

I've got some others I'll find and post later. My wife's trying to get my ass out the door to "go shopping" now.

Later:
Here's a phantom supply with discrete components. With this or the first one above, you'd need to tap into the secondary AC of the power transformer at 25-30vac.

or

Here's a schematic from the above site with both 24 and 48v supplies. You can run both from an external AC 24v wall wart, or you could as easily incorporate 115 primary/24v secondary transformer which are cheap and available.

THANKS for the link

I know I was there once, what seems a long time ago

Great links, all of them, Crazy-Doc!
I knew I had been to SeventhCircles before, I just didn't have the link.

Thanks for the help.
