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 90% of its set value, after the input voltage is removed.

Dynamic Response

The power supply output voltage will remain within ±5% of its

steady state value, when subjected to a dynamic load 50 to 100%

of its rated current.

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.

Overvoltage Protection

The power supply’s overvoltage circuit will be activated when its

internal feedback circuit fails. The output voltage shall not exceed

its specifications defined on Page 6 under “Protections”. Power

supply will latch off, and require removal/re-application of input

AC voltage in order to restart.

All parameters are specified at 25°C ambient unless otherwise noted.
