Crest Factor (CF)
The crest factor stands for a ratio of the rms value
correlated to the peak value (crest value) of the
waveform.
Equation:
Note
The crest factor is 1.41 of sine wave.
Inrush Current
Capacity
It indicates the current, which is able to be supplied
to a load, exceeds the rating for a short period and
the duration.
Output Power
Ratio
It indicates the output power of a percentage where
the rated maximum output power is 100%.
Alarms
The ASR-2000 series have a number of protection features. When
one of the protection alarms is tripped, the ALM icon on the
display will be lit and the type of alarm that has been tripped will
be shown on the display. When an alarm has been tripped the
output will be automatically turned off. For details on how to clear
an alarm or to set the protection modes, please see page 195.
Abnormal Output
This alarm is activated and output will be disabled
immediately when output overvoltage or
overcurrent is detected.
Abnormal Power
Source Block
This alarm is activated and output will be disabled
immediately when internal power source
abnormality is detected. Beware that all operations
will be disabled except for the power shutdown
operation if an error occurs.
