Fall Time
For a programmed 95% to 5% step in output voltage.
Time Delay From Power On Until Output Stable
5 s maximum
(Within regulation envelope)
Time Delay From Output Enable Until Output Stable
2 s maximum
(Within regulation envelope)
Output Hold-Up Time – Power Off
Minimum 4 ms (at full load)
Output Hold-Up Time – Source Interruption
Minimum 4 ms with output deviation less than 5% of maximum output voltage after
source interruption.
Transient Response Time
1
Time to recover within 0.75% of rated output of previous level after step change in
load current between 50% and 100%.
Mode Crossover
Maximum deviation as a percentage of rated output voltage.
Peak–Peak and RMS Noise Bandwidth Limits
The frequency range for Peak to Peak measurements is 10 Hz–20 MHz.
The frequency range for RMS measurements is 10 Hz–100 kHz.
