STK4131V
Specified Transformer Power Supply (RP-25 equivalent)
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 shorted 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.
