GENERAL CHARACTERISTICS
a-c Line Power Input 120 VAC ±10%, 50/60 Hz or
240 VAC ±10%, 50/60 Hz
120V is factory default; 240V requires internal
configuration (see PAR 2.3.1)
Cooling Forced Air (400 CFM) Variable speed fans, cooling determined by load
demand.
Operating Tempera-
ture 0°C to 40°C
Dimensions (load) 19”W x 7”H x 24.5”D See Figure 2-10.
Weight (load) 88 lbs.
Storage Requirements –20 to +60°C, 15 to 80% RH Relatively dust free environment
NOTE:
(1) Regulation specified after 15 minutes of operation at set power level.
(2) Accuracy and regulation are valid from 5% to 100% of the rated value. The accuracy (e.g., ±0.25% of a constant current setpoint)
is ±0.25% of the full scale value and not the setpoint.
