|English term or phrase: derating|
|Definition from Martek Power Abbott, Inc.:|
Reducing one operating parameter to compensate for changes in other parameters to maintain reliability. For example, the reduction in output power at elevated temperatures.
- Two things can be inferred from these ratings: the maximum storage temperature is equal to the derated temperature. Also, the slope of the derating can be used to calculate an equivalent thermal resistance in degrees C per watt. The difference between the no-load and maximum full load temperature is less than or equal to the temperature rise at full load. P-N Designs, Inc.
- Most dc/c manufacturers have design-derating guidelines, but sometimes designers use guidelines they have developed themselves. As engineers, we derate components to improve their reliability by decreasing component stress. Hearst Business Communications, Inc
- A derating chart is often used, with derating starting at 70oC. Since parameters are application dependent, power de-rating curves or charts should be considered general rather than absolute, and only used as a guideline. interfacebus.com
