Functions
Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
Start-up Time
The time required for the output voltage to reach 90% of its final steady state 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 final steady state set value.
Hold-up Time
Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value.
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 remains within ±10% of its
steady state value, when subjected to a dynamic load from 10% to
100% of its rated current.
