Yesterday, we got the boards back from the PCB fab house. Today, I built the FAB1215 prototype and tested it. Now, we have a power supply to power all our FAB modules. Yay!
This convenient power supply is powered by a simple 12VDC power adapter (wall wart). The one I’m using is rated 400mA and it’s the only one I can scrounge around… but I’d recommend a 1Amp power adapter so you have plenty of power to spare.
The +/-15Volts is generated by an off-the-shelf part, and the +48Volts for phantom power is generated by our DC-1248 Module (12VDC to 48VDC converter).
The FAB1215 has (1) DC jack to accept the 12Volts input, and (2) IDC headers that route +/-15Volts, and +48Volts so you can power (2) channels of your project. The +/-15V is rated up to 190mA, and the 48Volts is rated up to 60mA (this 60mA figure may change once I finalized on the component values and complete testing). You simply hookup power using 10-pin ribbon cables to your FABs. It’s that easy.
