Specified Transformer Power Supply

(Equivalent to RP-25)

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 output

noise voltage, use the specified transformer power supply shown below.

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.
