Table 9-16: Normal Voltage Maximum
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 9-17 with 5 seconds
