1 200/208 Vac input reduces the current and power rating 50%; 200/208 Vac input is only available with firmware rev B.06.03.1003 and up
2 Applies for ambient temperatures above 30°C or below 20°C
3 From occurrence of over-voltage to start of shutdown
4 With no load and a step change from 0.1% to 100% of voltage rating; bandwidth frequency = 100 kHz
5 With ac short and a step >10% of output voltage rating; bandwidth frequency = 100 kHz
6 With load voltage = 50% of voltage rating and a step change from 0 to 100% of voltage rating; load ESR= 0 Ω; load ESL = 0 µH
Bandwidth parameters are set as follows: Vmin = 25% of voltage rating; Lsense = default; Frequency = 100 kHz
7 Time from when the Output On command is received to the initiation of turning the output on
8
Unit is susceptible to internal damage if Maximum Load Inductance limits are exceeded at the rated current
9 Due to the pre-regulation circuits in the unit, the line regulation is not measurable
