5.1 Temperature
5.2 Humidity
5.3 Altitude
5.4 Mechanical Shock
The power supply (non-operating) shall not be damaged during a shock of 50G with an 11
mS half sin wave when non-operating. The shock to be applied in each of the orthogonal
axes.
5.5 Vibration (Operating and Non-operating)
The power supply shall be subjected to a vibration test consisting of a 10 to 300 Hz sweep at
a constant acceleration of 2.0g for duration of one (1) hour for each of the perpendicular
axes X, Y and Z,
1. 0.1 octave/minute. The output voltages shall remain within specification.
5.6 Acoustic Noise
The power supply shall be tested in accordance with specifications. The overall sound is
measured with the noise meter placed 1 meter from the nearest vertical surface of center of
fan installed in power supply.
