This test will change the output voltage from 28V or 14V to 30.3V or 15.1V. The test will last for
30 minutes. The (backspace) will terminate the test at any time.
VOLT UNDER
This test applies to category Z and 28 volt category B equipment. The output voltage will drop to
10 volts and will ramp up at a rate of 0.15 volt/sec for the US standard and at a rate of 0.30
volt/sec for EUROCAE standard for 30 seconds before it returns to nominal value.
VOLT SURGE
This test will surge and sag the voltage to a level and duration specified Table 8-15 with 5
seconds between transients. The test is repeated three times.
