Hi amigos,
Just got this Pass A3 modules. I want to build a double Mono board.
But looking for the appropriate Toroïdal PSU.
Recommend PSU is : AC20V-0-AC20V
I am pretty lost with those Toroïdal stuff... I have one 300VA with 2x17V secondary but I guess it is nor the right one....
TTS300/D230/17-17V BREVE TUFVASSONS - Transformateur: toroidal | 300VA; 230VAC; 17V; 17V; 8,82A; 8,82A | TME - Composants electroniques)
The AC input board has 3 faston inputs, any idea ?
Can someone give any appropriate Link (Europe would be better) :
I found this but I don't want to buy via Aliexpress...

I also fogot to ask :
Can I connect a + - 30V SMPS 300W (30-0-30 VDC) to the AC module input ?
Usually 20 V AC = 30 V DC
So I guess that I can use any SMSP 30V DC double rail / 300W and the Diode Bridge will automatically convert DC to AC and vis versa.
SMPS 300RS (double rail) :

Can you show me with a picture ?
I I wire 2x20, I will only get one 20-0-20 ?
I have two boards... so I need 20-0-20 x 2

For something like your boards with rectifiers built in, it's probably simplest to use two
transformers.
The general idea is given here:
https://www.electronics-tutorials.ws/transformer/multiple-winding-transformers.html
Look at the "series connected secondary transformer" The "link" on the secondary
side forms the centre-tap. The page also mentions this fact a bit further down.
Note it is important to connect the secondaries in the correct phase. The transformer
manufacturer should supply the proper wiring diagram.
