7-5. PROGRAMMABLE POWER SUPPLY ASSEMBLY 1A3
7 - 5
INPUT CODE: PPSST
a. DESCRIPTION
This module tests programmable power supplies 1A3PS1, 1A3PS2, 1A3PS3, and
1A3PS4. Each of the programmable power supplies is programmed and checked at three
different dc voltages and currents. The output voltage, load resistance, and noise
(ac ripple) are measured and compared to upper and lower limits. The output current
is calculated from the measured voltage and load resistance, and compared to upper
and lower limits.
A prompt is displayed at the completion of the test if an error is detected.
b. REPLACEMENT PROCEDURE REFERENCE
The following list provides a cross reference of replacement items to
replacement procedures.
The item column identifies the item to be replaced by
reference designation and part number.
The reference column identifies the
