Note *1. 1channel operation. *2. All tests are measured using a constant-voltage supply unless otherwise specified *3. The output noise voltage is peak value of an average-reading meter with a rms value scale (VTVM).
A regulated AC supply (50Hz) should be used to eliminate the effects of AC primary line flicker noise *4. Allowable time for load short-circuit and output noise voltage are measured using the specified transformer pow.
