Power Supply
Powering the rack by converting a 9V to 36V input into +12V, -12V and +5V.
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.
