Unless otherwise specified, the terms "voltage" and "current" refer to the effective value (r. m. s). The rated voltage is the voltage specified by the manufacturer for the appliance. The rated voltage range is the voltage range specified by the manufacturer for the appliance, represented by its upper and lower limits. The highest voltage that a working voltage appliance can withstand when operating at rated voltage and under normal working conditions. Note 1: Consider the influence of different positions of controllers and switching devices. Note 2: The working voltage takes into account the resonant voltage. Note 3: When determining the working voltage, the influence of instantaneous voltage can be ignored. Rated power input is the input power specified by the manufacturer for the appliance. The rated power input range is the input power range specified by the manufacturer for the appliance, represented by its upper and lower limits. The rated current is the current specified by the manufacturer for the appliance. Note: If no current is specified for the appliance, the rated current: - For electric heating appliances, the current value calculated from the rated input power and rated voltage; --- For electric appliances and combination appliances, the current value measured when the appliance is operating at rated voltage under normal working conditions. Rated frequency is the frequency specified by the manufacturer for the appliance. The rated frequency range is the frequency range specified by the manufacturer for the appliance, represented by its upper and lower limits. Normal operation: The state in which an appliance operates normally when connected to a power source
