A.4 Environmental Requirements
The power supply will be compliant with each item in this specification
for the following Environmental conditions.
Temperature Range
Operating 0 to +50 deg. C
Storage -20 to +80 deg. C
Humidity
Operating 5~95% RH, Non-condensing
Storage 5~95% RH, Non-condensing
Vibration
The subject power supplies will withstand the following imposed
conditions without experiencing non-recoverable failure or deviation from
specified output characteristics.
Vibration Operating – Sine wave excited, 0.5G maximum acceleration,
10~250Hz 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 text experiences excursions two times large than
non-resonant excursions.
Plane of vibration to be along three mutually perpendicular axes.
Shock
The subject power supplies will withstand the following imposed
conditions without experiencing non-recoverable failure or deviation from
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.
Cooling Specifications
