The manual states I need the following analog power supply:

0.3A @ +12 to +15V (4.5W)
0.25A @ -12 to -15V (3.8W)
The positive supply – +12V to +15V – should be brought in on the A+15V line on pin 59.
The negative supply – 12 to -15V – should be brought in on the A-15V line on pin 60.
The analog common should be brought in on the AGND line on pin 58.
​

I plan on using the 34V 3A version of this:

Can someone confirm that this will work, and describe the circuit needed?
Thanks

 

Should say 24v not 34!

 

To get ±12V from a 24V supply you need a rail-splitter circuit.
Here are some ways to do that.

If either the supply or load is floating; you can use a splitter as crutschow says. If the current is pretty much constant; you might get away with a simple voltage divider. If the load is more unpredictable, you can buffer the resistor divider with an op-amp - for the current you mentioned; you will need to buffer the op-amp with a complementary pair of power transistors in emitter follower. You have to include the transistors in the op-amp nfb loop to make them behave.

 

I've decided to just get a +/-12v power supply instead.

 

Though I was wondering, could I use a 12v and a 24v power supply, with a common +rail, and the 0v rail of the 12v supply connected to GND?

For 300mA - you can probably get away with a pair of wall-warts.

They're usually double insulated with no internal earth connection to the low voltage side.

If its only 2 pin, you're all set. 3 pin wall warts often have a plastic earth pin that's only there to open the safety shutters on the wall socket.

Very few wall warts have a brass earth pin - its simple enough to check no continuity to the low voltage side.

 

I actually already have a 12 & 24v supply, I just wondered if there are any issues with connecting them as described?

Yes, that will work, provided they are both transformer based supplies and both are floating.

No, because the current from the +24V supply would have to flow through the +12V supply backwards and a typical power supply cannot sink current unless they are expressly designed to do so.

Darn!
Thanks anyway.
