This power supply generally stacks underneath all SBC modules developed and for those to follow. It is supplied through a 120VAC detachable plug-in to an isolated receptacle. The circuit breaker is protected with bottom-side fische paper to insulate against harmful voltages. The module produces a +/-15V (500mA) and +5V output at 3A. +5V for digital logic module support. +/-15V for analog line level module support.
No power switch, just plug in and go.
