E.4 Power Supply
(
The power supply is a selt-contained assembly that provides DC
voltage tor the SUPER STAR system. The power supply provides + 8
Vdc
and both + 16 Vdc and - 16 Vdc to the SUPER STAR motherboard
which in turn supplied power to allot the printed circuit boards
plugged into the motherboard. The power supply also provides +
12 VdC and + 5 Vdc to the tloppy disk drive assembly and + 5 vac
and both + and - 12 vac to the hard disk drive.
The three DC voltages supplied to the motherboard are tused
inside the power supply as tollows: + 8 vac has a 20 amp
tuse, + 16 Vdc has a 2 amp tuse and - 16 Vdc has a 2 amp tuse.
The tloppy disk drive and hard disk drive DC voltages, supplied
by the power supply are not tused because the DC power input line
to these assemblies have their own tuses.
Figure E-2 is a schematic diagram ot the SUPER STAR power supply.
The rating tor tuses and output voltages are identitied in the
schematic. Values tor resistors, capacitors and other components
ot the power supply can be tound in Appendix F ot this manual.
