Notes. All tests are measured using a constant-voltage supply unless otherwise specified. 1. Available time for load short-circuit and output noise voltage are measured using the transformer supply specified below. 2. The output noise voltage is the peak value of an average-reading meter with an rms value scale. The noise voltage waveform does not inlcude any pulse noise.
