Turn-On Rise Time
Output voltage overshoot/undershoot at turn-on.
Varies by output. Total regulation includes: line changes from 85-132 VAC or
170-264 VAC, changes in load starting at 20% load and changing to 100% load.
Recovery time, to within 1% of initial set point due to a 50-100% load change,
3% max. deviation. (Main output only on multi-output units).
Time required for initial output voltage stabilization.
Time required for output voltage to rise from 10% to 90%.
