PSU for AOUT Module

Recommended Posts

Hi guys,

 

I am currently looking for a PSU suitable for an AOUT module. I saw the bulk order for the Meanwell RPT-60B and wonder if this works well together with the AOUT:

Can anybody confirm whether this works fine on an AOUT module or not ?

 

I also found a linear bipolar one from Doepfer, which is very expensive and I wonder if there are other options out there:

 

Doepfer A-100 PSU2

I would appreciate if we could collect the PSU’s in this thread suitable for the AOUT

 

Cheers

AOUT only requires +12v, GND and -12v, +5V is delivered by the Core in the default configuration. Any PSU that delivers those voltages will work. If you choose a switching PSU like the Mean Well it is good practice to place some capacitors between the PSU and your project. Also mind the switching frequency.

 

The Mean Well has a separate +5v line that could be connected to the AOUT board, but then it would be wise not to connect the +5v from the Core to the AOUT.

ok, so you can supply the core32 as well as the AOUT with one PSU ? It is just important to connect the +5V for the AOUT either directly from the Meanwell or indirectly through the Core32, correct ?

 

If you supply the Core32 from the +5V rail of the meanwell, do you still need a voltage 5V regulator on the core board ?

@mwidhalm: the datasheet says nothing about the switching frequency of that PSU (or at least I couldnt find it). Beware that it might be in the audio range.

 

@latigid on: if it would be possible to create -12v from +5v with your suggested solution, you still would need to power additional modules that you need the CV signals for. If those are in another box with a separate PSU it might work, I'm no expert. At least I would rather buy a known good psu than tinker with something else, I've had too many PSU related issues that put me off completely for a good while.

I'm about to use Recom RS-0512D in another project (being able to convert 5V to +/-12V), also, it's being used in mistralXG design (and I assume successfully) that was discussed some time ago. Maybe definitely worth a try but it's only up to 3W, which still should be plenty for few opamps.

Hope this helps,

From Mouser there are 0.5W and 1W solutions for 10,39 and 18,26€ respectively. 70 kHz switching frequency, which I would hope to be high enough to avoid problems, but I'm not sure! The Recom unit seems to have a higher switching frequency of 100 kHz or more, so it is probably better in that regard.
