Notes
Use rated power supply for test unless otherwise specified.
When measuring permissible load short time and output noise voltage use transformer power supply indicated below.
Output noise voltage is represented by the peak value rms (VTVM) for mean reading. Use an AC stabilized power
supply (50 Hz) on the primary side to eliminate the effect of AC flicker noise.
