Functions

Start-up Time

The time required for the output voltage to reach 90% of its set value, after the input voltage is applied.

Rise Time

The time required for the output voltage to change from 10% to 90% of its set value.

Hold-up Time

Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time

required for the output to reach 95% of its set value, after the input voltage is removed.

Inrush Current

Inrush current is the peak, instantaneous, input current measured

and, occurs when the input voltage is first applied. For AC input

voltages, the maximum peak value of inrush current will occur

during the first half cycle of the applied AC voltage. This peak

value decreases exponentially during subsequent cycles of AC

voltage.

Dynamic Response

The power supply output voltage will remain within ±1500mVpp of

its steady state value, when subjected to a dynamic load from

10 to 50% and 50 to 100% of its rated current.
