Clause 3 – How to understand the definition of “rated power input range”

rated power input range: power input range assigned to the appliance by the manufacturer, expressed by its lower and upper limits.

This definition corresponds to the rated voltage range, which means that the rated power input is labeled with a range of upper and lower limits.
Example: A quartz tube room heater with a rated voltage range of AC220-240V and a rated power input range of 2000-2200W.
