KDC Series II DC Power Supplies
2. 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
3. Stay at 31.5V for 92.242 seconds before returning to 28V.
270V system:
1. 350V for 50msec.
2. The voltage gradually decays with time to 290 volts by the following equation:
V = 289.6 + 3.02/t. for 0.05 t 7.55
3. Stay at 290V for 92.45 seconds before returning to 270V.
Prior to the test, a range change may take place if the power source is set at the low voltage
range. Note: See paragraph 11.2.9 under HIGH VOLTAGE.
The
key (backspace) will terminate the test at any time.
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.
UNDER VOLTAGE
This test will change the output voltage for the selected phase in the following sequence:
28V system:
1. 0V for 7sec.
2. 20V for 93sec.
270V system:
1. 0V for 7sec.
2. 240V for 93sec.
The
key (backspace) will terminate the test at any time.
11.2.11 Emergency Test
From the MIL704 DC MENU scroll to the EMERGENCY TEST entry using the up and down
cursor keys (Figure 11-11). Note that there is no submenu below this entry as there is only one
Emergency test step. Press the ENTER key to start the EMERGENCY TEST.
Figure 11-11: Emergency Test
VOLTAGE
This test will change the output voltage for the selected phase in the following sequence:
28V system:
1. 18V for 1 minute.
2. 29V for 1 minute.
3. 28V for 1 minute.
270V system:
1. 250V for 1 minute.
