Electrical Specifications
Absolute Maximum Ratings
Stress in excess of those listed in the “Absolute Maximum Ratings” may cause permanent damage to the power supply.
These are stress ratings only and functional operation of the unit is not implied at these or any other conditions above
those given in the operational sections of this TRN. Exposure to any absolute maximum rated condition for extended
periods may adversely affect the power supply’s reliability.
