如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured.
给变频器的输入端送交流电，发现变频器的操作面板没有显示。
Give frequency converter input send ac inverter, found the operation panel not shown.
高功率因数稳压电源是一种既能起到稳压作用又可以提高电源输入端功率因数的高性能交流电源。
High power factor stabilized voltage supply is a kind of high performance alternating current power supply which can not only steady the output voltage but also enhance the input power factor.
特别注意不要将交流电联接在低压控制输入端，比如传感器输入端、逻辑输入与输出端口。
Take particular care not to connect AC supplies to low voltage control inputs such as sensor inputs, logic inputs and outputs.
