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.
Here is the power supply I made from scratch to support the various modules developed so far. With more to come, this unit is sure to prove useful again and again. A fundamental layer module for various units that are developed; both analog and digital.
This is a power supply module with +/- 15V and +5V output ports. The module hosts a low-profile switching power supply (SPS) soldered and bolted in place for high board retention. At the output of the module is a screw-locking terminal strip for each available voltage point. To include reference designators as printed on the circuit board for ease of identification and termination. The power LED illuminates as an AC input voltage is applied.
An AC source voltage is supported with a male 3-point plug-detachable receptacle for a 115VAC 60Hz input. This unit comes with a matching male plug for safe and fully insulated AC connectivity. The module is fitted with a 3A circuit breaker that provides added protection between the SPS and its source.
