1·It will not generate 'mains voltage' or 'utility power' AC.
它不会产生'电源电压'。
2·This is basically a reading of how efficient the PSU is at turning AC mains voltage into DC for your PC.
这基本上是一个如何在高效率的电源供应器变成直流电源为您的PC交流电压读数。
3·Mains voltage heating cables shall be adequately insulated and installed in complinance with the relevant Regulations.
供电电压的电热线应依照有关条例恰当地绝缘和装设。
4·The operating value of earth leakage protection can be changed with the mains voltage, but the operating value of cables insulation resistance is held the line.
该设计可以根据电网电压的波动调整动作值，从而保证电缆绝缘电阻的动作值不变；
5·The analysis and treatment of trouble of high-voltage circuit system are carried out through instance, and the effect of mains voltage fluctuation on equipment is also inquired initially.
对高压电路系统故障的实例进行了故障原因分析和处理，并对电源电压波动对仪器的影响进行了初步的探讨。
6·Now the first mains-voltage LEDs designed as direct replacements for incandescent bulbs are arriving on the market.
如今首批设计的民用电网电压的能直接替代白炽灯泡的发光二极管已陆续上市.
7·Therefore it can be seen that it will "smooth" the "twice mains frequency DC" into a near constant DC voltage.
因此它可以把“两倍于电源频率的直流电”进行“平滑化处理”，成为一个接近恒定的直流电。
