2.2 HOLD-UP TIME: 16ms(minimum)
Test Condition: Full load. AC input 115V or 230V, 47Hz .
2.3 LOAD TRANSIENT RESPONSE (STEP LOAD)
Step load changes up to 60%(12V) and 30%(3.3V and 5V) of full load, while other loads remains
constant within the rating. The load waveform shall be a square wave with the slope of the rise and
fall at 1.0A/usec and the frequency shall be from 50Hz to 10kHz. The DC output voltage will stay
within regulation of ±5% during the step load changes.
2.4 OVERSHOOT
Overshoot at turn on or turn off shall be less than 10% of the nominal output voltage.
