4.4.2.1 MIL-STD-704D TRANSIENT PROGRAMS (cont)
OVER-FREQUENCY TRANSIENT (Program #102)
The power source will produce the over-frequency transient excursion as defined by MIL-STD-704D
(Paragraph 5.2.3.2.1). The power source
must
be configured for a voltage range of at least 115Vrms to
perform this test.
