Note : For power supply at the time of test, use a constant-voltage power supply
unless otherwise specified.
* For measurement of the available time for load short-circuit and output
noise voltage, use the specified transformer power supply shown right.
** The output noise voltage is represented by the peak value on rms scale
(VTVM) of average value indicating type. For AC power supply, use an AC
stabilized power supply (50Hz) to eliminate the effect of flicker noise in AC
primary line.
