تعريف herabsetzen der betriebswerte في ألمانية الإنجليزية القاموس.

derating

(Elektrik, Elektronik) Derating is the technique employed in power electrical and electronic devices wherein the devices are operated at less than their rated maximum power dissipation taking into consideration the case/body temperature, ambient temperature and the type of cooling mechanism used

A reduction in a generating unit's Net Dependable Capacity

A specified reduction in output power at elevated temperatures to improve reliability

The reduction of the amount of wattage used to prevent overheating Related to ganging of dimmers

present participle of derate

The reduction in a system's performance resulting from operating conditions other than nominally specified, including temperature, output load, or input voltage

For a power converter, the specified reduction in output power required for operation at elevated temperatures The most common operating temperature range specified for commercial grade converters is 0°C to +70°C without derating See Cooling, Convection Cooling, Conduction Cooling, Free Convection and Forced Air Cooling

The design practice of reducing stress levels that could cause premature failure of electronic piece parts by assuring that the parts will operate at stress levels below the manufacturer's rated values For example, capacitors are derated by maintaining the applied voltage at a lower value than the voltage for which the part is rated

– For an AC-DC power supply, the specified reduction in output power required for operation at elevated temperatures The most common operating temperature range specified for commercial grade power supply is 0ºC to +50ºC without derating Also see Convection Cooled

reducing one operating parameter to compensate for changes in other parameters to maintain reliability For example, the reduction in output power at elevated temperatures

Reducing the capacity of a control when side sections are removed

A reduction in the power output capacity of a power supply due to its external environment such as altitude, airflow and ambient temperature

-Calculations that reduce standard tabulated ratings based, generally based on ambient temperature or proximity to a heat source
