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


     
  High_voltage_warning.svg.png 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 AC mains (house) power.
Before opening the power supply, adequately educate yourself as to the hazards.
Some hazard examples at here.


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

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