Electromagnetic compatibility - limits - limitation of voltage fluctuations and flicker in low - voltage power supply systems for equipment with rated current greater than 16a 电磁兼容限值对额定电流大于16a的设备在低压供电系统中产生的电压波动和闪烁的限制
This will avoid the trouble of hand operation and protect people ' s eyes by its special fuction of maintaining the light stability under fluctuate voltage 即可减少手动调光的麻烦，又可以保护视力，同时，它具有稳光功能，当电源电压波动时，台灯亮度保持不变。
You cannot switch thebutton to the faster level directly from the stop status to keep the voltage jump within usb limits ( 500ma ) during motor start up 为了保证吸尘器电机启动时电压波动在usb接口限制的范围（ 500毫安）内，不能直接将开关从停止位置打到快速档。
Electromagnetic compatibility - limits - limitation of voltage fluctuations and flicker in low - voltage power supply systems for equipment with rated current greater than 16 a 电磁兼容性.第3部分:极限.第5节:额定电流大于16a设备用低压电源系统对电压波动和闪烁的限制
In electronics , a circuit for converting ac voltage to low voltage dc in such a way that the output is regulated to minimize noise and voltage fluctuation 在电子技术中,把交流电转换成低电压直流电的一种电路。这种电路的输出是经过调整的,使它的噪声及电压波动都很小。
According to iec ' s standards involved , voltage fluctuation and flicker become a index of power quality . but the research in those aspects such as harmonic frequency excursion and ect 然而，人们对于电能质量中诸如谐波、频率偏移等方面的研究相对电压波动和闪变来说要多得多，研究得也较成熟。
Electromagnetic compatibility - limits - limitation of voltage changes , voltage fluctuations and flicker in public low - voltage supply systems , for equipment with rated current 16 a per phase and not subject to conditional connection 电磁兼容性.极限值.额定电流为16a低压供电装置电压波动极限值
At present , our country power quality national standard was chiefly stipulated five quotas : frequency , harmonic and voltage deviation , three - phase unbalance and the voltage fluctuation and flicker 目前我国电能质量国家标准主要规定了五个指标：频率、谐波、电压偏差、三相不平衡及电压波动与闪变。
In order to solve this problem , this paper introduces a reading lamp which can change the lighteness automatically . it has a photodetector which will be put near the book to help adjusting the brightness data 即可减少手动调光的麻烦，又可以保护视力，同时，它具有稳光功能，当电源电压波动时，台灯亮度保持不变。
