CUS150M Handbook
Convection and conduction/cold plate Cooling (U chassis and open frame) max ambient 80°C (note 1)
Fan supplied ratings/Option F max ambient 70°C, from 50°C to 70°C the output power is de-rated by 0.5°C per
watt
Note 1:.Maximum output power and current ratings are dependent on the ambient used in the end
equipment. Please see power curves for guidance.
