Power Supply Modul~ Rev SEP-06-77




1.0 INTRODUCTION.
The Pow~r Supply Module generates the following required voltages for
the 264XX Data Terminal product line: +5 volts at 12 amperes, +12
volts at 1.5 amperes, -12 volts at 1.5 amperes, and -42 volts at 0.6
amperes. Either one of the 12-volt supplies may be loaded to 3
amperes continuouslY, as long as the other 12-volt supply current is
reduced so tnat the total current from both supplies does notexceed
3 amperes. The maximum total power of all voltage outputs must not
exceed 110 Watts. Parts list for 02640-60083 is contained in module
section 13255-91004.

2.0 OPERATING PARAMEfERS.
A summary of operating parameters for the Power Supply Module is
contained in tables 1.0 through 3.1.
