Note:
The nouns, parameters and corresponding test methods in this parameter list conform to the standards of IEC60099-4:2014 and GB11032-2020.
The rated voltage, power frequency reference current and power frequency reference voltage are reference values.
The 2ms square wave tolerance value is based on the declared current/2ms repetitive charge transfer charge Qrs=423, if the actual test waveform 2ms current/2mS repetitive charge transfer charge Qrs is not equal to 423, it should be corrected according to the actual 2ms current waveform and Qrs value.
The charging rate of the aging test was 90%.
The number of pulses for the high current withstand value is two.
