No. 2322—2/8

Notes.

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 out-

put 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.
