Power Supply

Status: Built

My power supply is based on the Erica Synths mki x es.EDU Power Supply. I created a 6 HP rack mount clone so I could bring the power switch and status LEDs forward to the front of the rack. Why hide the blinkenlights inside the case?

The design is centered around a 12 volt DC to DC converter which means that I don’t need to worry about messing around with line voltage inside my case. The converter I’m using is the MORNSUN URA2412LD-30WR3 which is rated for 1.25 amps on each rail.

Future Improvements

• When I need to expand my case, I want to add some internal jacks so I can daisy chain multiple power supplies together off of a single DC wall wart.
• 5V power is currently supplied by a 78L05 which is pretty inefficient when stepping 12V down to 5V, in the next version I plan on using a buck converter for conversion.
