Notes
Use a constant voltage power supply for the test power supply unless otherwise noted.
Use the transformer power supply shown in the figure above when measuring the available time for load short circuit and the output noise voltage.
The output noise voltage is the peak value measured with an averaging rms scale volt meter (VTVM). A 50 Hz AC stabilized power supply should be used
to eliminate the effects of AC primary line flicker noise when an AC power supply is used.
