Crest Factor Sample Clauses
The Crest Factor clause defines the maximum allowable ratio between the peak and the average (RMS) value of a signal, typically in the context of electrical or audio systems. In practice, this clause sets a specific limit on how much higher the instantaneous peaks can be compared to the average power or voltage, ensuring that equipment is not subjected to damaging or unexpected surges. By establishing this threshold, the clause helps protect devices from excessive stress and ensures consistent performance, thereby reducing the risk of equipment failure or degradation.
Crest Factor. It is important to understand that electronic equipment, such as scanners, typically draws current in a waveform different from typical sinusoidal current.3 Figure 1 shows the typical current waveform for an electronic product containing a switching power supply. While virtually any meter can measure a standard current waveform, it is more difficult to select a meter when irregular current waveforms are involved. 2 True power is defined as (volts)x(amps)x(power factor), and is typically reported as ▇▇▇▇▇. Apparent Power is defined as (volts)x(amps) and is usually expressed in terms of VA or volt-amps. The power factor for equipment with switching power supplies is always less than 1.0; thus, true power is always less than apparent power.
