De-rating shall be less than the rating of the adapter's critical component, following FSP specifications.
Performance Curves
Input Voltage Derating Curve
This curve illustrates the output power percentage relative to input voltage. The adapter maintains stable output power across the input voltage range of 90 VAC to 264 VAC.
Output Power Derating Curve
This curve shows the output power percentage relative to ambient temperature. The adapter operates at full capacity up to 40°C. Above 40°C, output power is derated, reaching approximately 55% of maximum load at 70°C.
