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。
most measurement, control, and data i/o signals are measurement category i and must not be directly connected to mains voltage or to voltage sources with high transient over-voltages.
大多数测量、控制和数据i/o信号为测量类别i,不可直接连接到电源电压或存在高瞬间过电压的电压源。
the method includes rectifying a mains voltage to produce a dc voltage and placing the dc voltage on a bus.
在被耦合到输出转换器的总线上施加该直流电压,该总线具有位于该总线的至少一个线路上的开关;
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。
