## **DERATING CURVES** 

Note:      5. With an AC input voltage between 85 ~ 100VAC/277 ~ 305VAC and a DC input between 120 ~ 140VDC/392 ~ 430VDC the output power must be derated as per the temperature derating curves. 

6. This product is suitable for applications using natural convection cooling; for applications in closed environment please consult CUI.
