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.
