The 75W output power rating for this AC/DC power supply is based on a convection rating with a cover fitted
Without a cover the rating would be 110W
The maximum 175W output power for this AC/DC power supply can only be obtained by use of a cooling fan giving 30 cfm forced air, with a cover fitted this would be 130 W
Derating from 50 to 70°C is 2.5% per °C
