Abnormal voltage test
MIL704D[A][B][C]
:ABNormal
:VOLTage
This test will combine Abnormal overvoltage and Abnormal undervoltage. There will be a pause of 5
seconds between tests. If the voltage range is below 180 volts the Abnormal overvoltage test will not
take place.

Hz
for
5
seconds
375
Hz
for
5
seconds
