FUNCTIONAL DESCRIPTION
The IMSAI PS-28D Assembly is a modular unregulated power supply
for the IMSAI 8080 System.
+8, +16, and -16 system supply voltages.
a 117 volt AC single-phase line input, and includes a line noise
filter.
117 volt terminals, both switched and unswitched, are
available for line powered options such as the ventilating fan
and auxiliary power outlets on the back panel.
location is provided on the PS-28D for use when a front panel
is not installed in the system.
Physically, the PS-28D measures 16.5" x 5.75" x 5.5",
x 14 cm), and weighs 16 pounds (7.3 kg).
