Salas low voltage shunt regulator (V 1.0)for DAC or other project!
Hello!

There are many member love the design of Salas and they require a low voltage pcb Salas again

I like most is vesiont 1, because I have used successfully in the DAC-END.

You can use the DAC, like I'm doing, or for other projects.

V 1.0 design by Salas

Information:

There are three sources that: 2 + and 1 -.

From 5V-30V, the current 10-200mA

So I open the group by making PCB design of low voltage Salas.

You can see Salas design in:http://www.diyaudio.com/forums/powe...listic-salas-low-voltage-shunt-regulator.html

And I use for DAC in:
http://www.diyaudio.com/forums/group-buys/155960-dac-end-andrea-ciuffoli-group-buys.html.

DAC End 2 - the AD1865N-K with single ended vacuum output stage

Since there is an e-commerce site in Quanghao's signature now, and his board GBs have become a steady venture, there is no logic of group buy essence anymore. There is a vendor forum area being offered by DIYA that the interested parties can ask for. Therefore Quanghao's GB threads are closing. Communicate directly for any outstanding commitments. :cop:

Edit: Quanghao asked and got a Vendor forum of his own, old threads moved here.

Salas Low voltage shunt --is this pcb available?

I visit the website and noted that there is no price for the pcb.
There are 3 outputs for this pcb ? The output voltage depends on ac input voltage or adjustment values on the board ?
Sorry for my ignorance

New Design PCb Salas low shunt

There are so many members want me to do this PCB. I find v1.0 very stable Salas low and very low noise. In this PCB you can use for projects ranging from 3 V to use 50v. with 3 outputs including 2 + and an early start - with a maximum response line 250-300ma! you can see by the pictures!

If you like you can show me please!

quanghao,
I hope you are not misnderstanding me, I am not asking you to split boards for sale. But for the DIYer to have the option of splitting the boards if needed. I guess I am asking if each section is laid individually. I think it's a good option to have on the boards.
