1 This collection provides a overview of power losses of a component during all operational stages defined in IEC 62744, independent whether the power consumption is caused by unintended losses or whether it is intended, e.g. for radiation or heating purposes.
2 The properties can be applied also for calculation of the energy efficiency of a component being defined by: ratio or other quantitative relationship between an output of performance, service, goods or energy, and an input of energy

3 IEC 61439-1 provides guidance to the calculation of power losses in closed assemblies, e.g. cubicles, when having the losses of the assembled components. |
