随着人们生活水平的提高,使用电脑的人越来越多。由于一些地方电网电压不够稳定,有的用户便给电脑配上稳压器,以求稳定电压,其结果却得不偿失。其实电脑对电压的要求不是十分严格,一般在180～240V之间都能可靠地工作。目前市场上一些稳压器,其内部电路是靠继电器通断来稳定电压。当市电电压发生较大波动或同一电网内其它大功率电器开启或关闭时,稳压器自动稳压电路会启 As people’s living standards improve, people use computers more and more. As the grid voltage in some places is not stable enough, some users provide the computer with a voltage regulator in order to stabilize the voltage, but the result is worth the candle. In fact, the computer voltage is not very strict requirements, generally between 180 ~ 240V can work reliably. Some regulators on the market today, the internal circuit is based on the relay off to stabilize the voltage. When the mains voltage fluctuations occur more or other high-power electrical appliances within the same grid on or off, the regulator will automatically turn on the voltage regulator
