I am looking for a triple output switching power supply. I would 
prefer to deal with manufacturing companies that can provide 
immediate technical assistance from in-house engineers.

The three outputs are...
1. 24v dc @ 1A
2. 24v dc @ 1A
3. 48v dc @ >0.1A

The second and third output should have a common 0v. The first output 
should be floating such that either polarity can be connected to either 
the other 24v or 0v to provide either a second +24v output or 
a +/-24v output.

The unit should auto sense the incoming ac voltage and not require a 
voltage selector switch. It should operated reliably and with 
minimal audio band noise at 100v ac input and 240v ac input.

The case dimensions should be approximate 160mm x 100mm x 38mm
