Default Dedicated PSU for DEQ/DCX2496

Hi Folks!

I'm designing a linear dedicated PSU for the Behringer DEQ2496 (and DCX).

I need an advice. In this current draft drawing, the 10v ground is connected to the 15v ground. I don't know if I can connect 2 ground lines for 2 different transformer/rectifier.

Enclosed is my last draft.

Thanks for your help.

Stephane

Stephane,

Didn't you already install a psu in your DEQ2496 a while back?

Sorry Vic, I'm not sure to understand your question.

New version. I started to design the PCB. VK200 will be removed (no space lelft for that). All rectifier will have caps close to the pins. I changed some components references. The schematic is not yet up to date.

Hi Stephane,
What is the improvement over existing PSU?Would this replace 7805 regs. that are on the board as well or they will stay?
Thank you

Never Mind - I see how this is different. You are going to replace the stock PSU altogether.
Thanks for sharing the project - this is one I would like to follow...

Yes, true.

New version. Heat sink was too small for 3.3v and 5v. VK200 are back. Decoupling caps for all rectifiers. Ground plane. 2 types of output connector possible.

Real size.
