Current Limit mode
Programmable, CC or CV mode
Note: Constant power mode allows higher current at reduced voltage. Maximum current available at 77% of
voltage range. See Figure 2-1 through Figure 2-6 for voltage versus current profiles by model and
voltage range.
Note: Full power output available only when using 208-230 AC nominal input line. For 100-115V AC input
operation, maximum output power and current are limited by maximum input current of 20 A.
