4.9. The main power supply shall be off when the PS_ON pin is floating
(open collector). The ON/STBY pin of P1 must remain off state for 5 Sec
(maximum) prior to switching to the ON state

5. FAN NOISE REQUIREMENTS

5.1.The subject power supply is cooled by a self-contained, 80mm×15mm,
12VDC fan.

6. ENVIRONMENTAL REQUIREMENTS

The power supply will be compliant with each item in this specification for the

following Environmental conditions.

6.1. TEMPERATURE RANGE

Operating +10 to +50 deg. C
Storage -20 to +80 deg. C

6.2. HUMIDITY

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.
