    • A power supply unit for use in a measuring instrument at a plant. An output from a current transformer mounted on a power supply line is controlled so that the range of a primary current producing a stable output is increased. The invention includes a current transformer mounted on a cable for providing power to an electric motor, and a power supply unit. The power supply unit includes a rectifier circuit, a short circuit, a reverse current inhibit element, a condenser, a voltage watching circuit, and a constant voltage element. The voltage watching circuit outputs a command signal when the voltage of the condenser exceeds a first level and connects the short circuit 32.
    • 用于工厂测量仪器的电源单元。 控制安装在电源线上的电流互感器的输出,使得产生稳定输出的初级电流的范围增加。 本发明包括安装在用于向电动机提供电力的电缆上的电流互感器和电源单元。 电源单元包括整流电路,短路,反向电流抑制元件,电容器,电压监视电路和恒压元件。 当电容器的电压超过第一电平并且连接短路32时,电压监视电路输出指令信号。
