AC input
Common ground of 0 volts of transformer secondary side
Power supply controller
Switching transistors
Primary side heat sink
Secondary side heat sink
0 V - black coated wires
Screwmount to chassis conducted
DC choke for +5 V und +12 V, placed flying over other devices. 3.3 volts DC choke on top
secondary rectifier +3.3 V, +5 V and +12 V
Pin 2 for Switch of Delon Bridge Circuit (Voltage Doubler). Voltage selector switch is
open: 230V were expected
closed: 115V were expected
(Damages occure if the higher voltage is connected when the lower voltage is selected.)
