额定电压范围 meaning in Chinese

range of nominal tension

The normal mains supply to the ballast shall be reduced within 0 . 5 s to 0 . 6 times rated voltage after which the emergency lamps shall operate
从正常到应急状态的转换应发生在不少于06倍额定电压、不能超过0 . 85倍的额定电压范围内。
Change over from normal to emergency mode shall occur at not less than 0 . 6 times rated supply voltage , it shall not occur at greater than 0 . 85 times rated supply voltage
从正常到应急状态的转换应发生在不少于06倍额定电压、不能超过0 . 85倍的额定电压范围内。
When the voltage of the primary fluctuated is within the range of 5 % , with mediating the saturation of the magnetic flux , this new interfluent stable power supply can retain the outputting power of the secondary invariable
当一次侧电压在5 %额定电压范围内波动或偏移时，通过调节磁路的饱和程度，保持二次侧输出电压不变。
