IBM 5160  -  Circuit diagram for IBM 130W power supply unit (PSU)


   
  WARNING:

Opening the 5160's PSU may expose you to hazardous voltages and currents.
Do not assume that those hazards will disappear shortly after disconnecting the PSU from mains (house) power.



Note that in the supply lifetime of the IBM 5160, there were variations of the PSU.  Some known differences follow:
• 110V AC versus 220V AC
• Different circuits due to different manufacturers

IBM did not provide circuit diagrams of the PSU in the 5160 manuals.  Accordingly, circuit diagrams are hard to come by.
