VOLT MIN
This test will set the voltage and frequency to levels defined by Table 9-12 for 5 minutes. The test will be
repeate
d for Group1 only as indicated in Table 9-12. All Groups will repeat the test using Table 9-12 for
the voltage setting and Table 9
test at any time.
VOLT UNBALANCE
This test applies only to RTCA2 standard.
Standard/Group
Voltage offset
Frequency
This test will change the output v
a value specified by an offset. Refer to Table 9-
will repeat with the same frequency and phase A and B volt is set to 97V and phase C set to a higher
voltage specified by the offset. The test will last 5 minutes. The test will be repeated for a second
Frequency if applicable. Additional test for A(C
122V and phase C at 116V. The frequency is set at 430V. The test is repeated with the same
frequency but phase A and B
370Hz.The test can be terminate
any time.
VOLT UNDER
This test will drop the output voltage from 115 volts to 60 volts for 7 seconds.
VOLT SURGE
This test requires 180 volt output voltage. If the power source is set at the low voltage range, the high
voltage range will be selected before the test starts. At the end of the test the AC source will be
switch
ed back to the low range.
The output voltage will surge to 180 volts for 100 ms. followed by drop to 148 volts for 1 sec before it
returns to 115 volts. The BACK key (backspace) will terminate the test at any time.
