POWER INTERRUPT

This test requires a numeric entry value equal to the test number. The tests are grouped as follows:

Test numbers 1 through 15 are for all Standard and Groups. See Figure 9-6 for details of the
tests.

Test numbers 16 and 17 for all equipment that does not incorporate digital circuit. Test number 16
will drop the output to zero voltage for 50 ms. Test number 17 will drop the output to zero voltage
for 200 ms. Test numbers 21 through 26 are applicable for Groups 2 and 3 only for EUROCAE
standard and category A(NF) and A(WF) for RTCA2. Output frequency will be set to the F1 value
for 1 second prior to the test. The output frequency will remain set to the F2 value when the test is
completed. This will allow the user to apply sequence of power interrupts. See Figure 9-7 for detail
of the tests.

NOTES

1:

Definitions:

T1

Power interrupt time

T2

Time it would take for the applied voltage to decay from V (nom) to zero volts.

T3

Time it would take for the applied voltage to rise from zero to V (nom) volts.

V MIN

The minimum level (expressed as a percentage of V NOMINAL) to which the applied voltage is
permitted to decay.

Equipment performance standards may require to repeat test n°1 with T1 varying from 5 to 200 ms by step defined in

the test equipment performance standards (step typically comprised between 5 ms and 20 ms depending on equipment
design.
