4.3 SHOCK AND VIBRATION

The power supply will withstand the following imposed conditions without experiencing

non-recoverable failure or deviation form specified output characteristics. Storage -40G,

11mSec. half-sine wave pulse in both directions on three mutually perpendicular axes.

Operating -10G, 11mSec. half-sine wave pulse in both directions on three mutually

perpendicular axes.Vibration Operation-Sine wave excited, 0.25G maximum acceleration.

10-250 Hz, swept at one octave/min. Fifteen minute dwell at all resonant points, where

resonance is defined as those exciting frequencies at which the device under test

experiences excursions two times large than non-resonant excursions.
