VECTOR 4
TECHNICAL INFORMATION
SECTION IX - OVERVIEW OF THE POWER SYSTEM
Summary: The SBC uses a switehing power supply. This self-contained
unit is located under the neck of the CRT.
The Interconnecting lines for the switching power supply are shown in Exhibit II-33.
The following table gives the specifications for the four output voltages/currents.
See the power supply distribution schematie (Exhibit VI-11) for a listing of the
pin-outs used by the two types of switching power supplies.
