MX15
159
Note:
A range change will result in momentary loss of power to the EUT. If this is not
acceptable, the power source must be left in high range at all times.
LOW VOLTAGE
This test will change the output voltage for the selected phase in the following sequence:
1. 28V System
•
18V for 15 msec.
•
Linearly increase to 22V in 85msec.
•
Stay at 22V for 75msec before returning to 28V.
2. 270V System
•
200V for 10 msec.
•
Linearly increase to 250V in 30msec.
•
Stay at 250V for 135msec before returning to 270V.
The
←
key (backspace) will terminate the test at any time.
9.4.8.3 Abnormal Test
From the MIL704 DC MENU scroll to the ABNORMAL DC entry using the up and down cursor
keys. Press the ENTER key to select the ABNORMAL screen. The screen will appear as
shown in Figure 9-18.
Figure 9-18: Abnormal Test Screen
The Abnormal Test has the following tests:
1
OVER VOLTAGE
2
UNDER VOLTAGE
The above tests can be selected by scrolling to the highlighted selection using the up and down
cursor keys and the ENTER key to start the selected test.
OVER VOLTAGE
This test will change the output voltage for the selected phase in the following sequence:
1. 28V system:
•
50V for 50msec.
•
The voltage gradually decays with time to 31.5 volts by the following equation:
V = 31.38 + 0.93/t. for 0.05
≤
t
≤
7.758
•
Stay at 31.5V for 92.242 seconds before returning to 28V.
2. 270V system:
•
350V for 50msec.
