The power supply will be compliant with each item in this specification for the following Environmental conditions.
6.1. TEMPERATURE RANGE
6.2. HUMIDITY
6.3. VIBRATION
The subject power supply will withstand the following imposed conditions without experiencing non-recoverable
failure or deviation from specified output characteristics.
Vibration Operating – Sine wave excited, 0.25 G 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.
Plane of vibration to be along three mutually perpendicular axes.
6.4 GROUND LEAKAGE CURRENT
The power supply groud leakage current shall be less than 3.5 mA.
