0.02%/°C of maximum output voltage rating for voltage set point. 0.03%/°C of
maximum output current rating for current set point.
0 to 50°C
-25° to 65°C
Internal fans; vents on sides and rear. (Units may be stacked without clearance
above or below).
95% maximum, non-condensing, 0 to 50°C; 45°C maximum wet-bulb
temperature
Operating full power available up to 5,000 feet (1,524m), derate 10% of full
power for every 1,000 feet higher; non-operating to 40,000 feet (12,192m)
Recommended long-term exposure limit is 0.1 PPM (0.2 mg/m3).
