Hi all!
Starting saying that I have very few notion of electronics (I work a lot with arduino and stuff but nothing more than that) so please be kind and patient.
So, I need to build a power supply, I need various voltages out of that for many audio equipment and I need space, so I can't use all the original suppliers from the manufacturers.
As I said I already have a small knowledge on circuit building, since now I always used low voltages on cheap equipment but now I don't have to power a 40€ Arduino anymore but 3k of extremely delicate sound equipment and I also I have to work with a lot higher voltages so I would like to not kill my equipment or myself (in that order).
What I need:
-Possibly a power supply that can work both on 110v and 230v.
-A lot of power.
-These voltages: (the ampere are a bit over the actual maximum need of the equipment)
9v (4 socket, 2A tot)
12v (2 socket, 2A tot)
15v (4 Socket, 4A tot)
-Protection on the outputs for over-current and short circuit.
-Thermal protection on the power supply.
-Extremely clean and stable power
-Extremely low noise on the circuit and on the equipment.
-Extremely isolation between all the equipment.
What I would like:
-A fan to cool down the case, but I a bit worried that can cause noise on the power, should I put some filter?)
-A led for each output to show the presence of tension or a fault.
-A switch for every output (not a really big deal)
-Maybe a temporized turn on for the various voltages (Do I need it? when I turn it on I can achieve a stable power or with that much load can lead to unstable voltages?)
This is what I thinked:
IEC Filter:

(shuld I need a rectifier here?)
Converter 110v/230v to 12v:

Converter 12v to 24v: (I would need these only if I use Linear voltages regulator)
http://it.rs-online.com/web/p/convertitori-cc-cc-isolati/8431673/
Or use something like this:
http://it.rs-online.com/web/p/alime...grati-smps/0446138/?origin=PSF_430700|alt(but I'm a bit afraid of the noise from a switching supplier)
Linear tension regulator: (here going from the 24v converter to 10 of these each regulated to he specific voltage)
http://it.rs-online.com/web/p/regolatori-di-tensione-lineari/5335840/
and here 10 different sockets for each power regulator.
Can work?
My questions:
Why I should use a linear power regulator and why a step down?
Es: http://it.rs-online.com/web/p/convertitori-cc-cc-isolati/1002643/
with the step down I wouldn't need the 24v converter but are a lot more expensive.
Thanks a lot in advance to everyone who will be so kind to help me!
