Power Factor Correction.
Peak-to-Peak Voltage Measurement.
PWR_OK is a "power good" signal used by the system power
supply to indicate that the +5VDC, +3.3 VDC and +12VDC
outputs are above the under-voltage thresholds of the power
supply.
The periodic or random signals over a frequency band of 0 Hz
to 20 MHz.
Rise time is defined as the time it takes any output voltage to
rise from 10% to 90% of its nominal voltage.
The condition where the AC line voltage rises above nominal
voltage.
An output voltage that is present whenever AC power is
applied to the AC inputs of the supply.
