WBV/I 121高速宽带跟踪型电量隔离传感器,是针对高压、大电流等强电,或负载能力很差的弱电,或幅值很小的信号,为克服其干扰、不宜直接与系统连接而设计的,分电压隔离或电流隔离2类。其工作原理是:当电压(电流)输入信号送至输入电路后,被转换成标准电压,并赋予较强的驱动能力;光电隔离电路实现输入信号的线性变换及隔离处理;输出电路将信号放大,输出具有较强驱动能力的标准电压以跟踪输入信号。传感器内部还配备了DC/DC转换器,从辅助电源+E提取能量供输入电路使用。并提供了传感器输出端接至后续设备的高速A/D等电路,信号由计算机等控制采样、处理,以及相应传递函数的应用示例。
WBV / I 121 high-speed broadband tracking power isolation sensor is for high voltage, high current and other strong electricity, or poor load capacity of weak electricity, or a very small amplitude signal to overcome its interference should not be directly connected with the system design Of the sub-voltage or current isolation 2 categories. Its working principle is: when the voltage (current) input signal sent to the input circuit, is converted into a standard voltage, and give a strong drive capability; optoelectronic isolation circuit to achieve linear transformation of the input signal and isolation processing; output signal amplification circuit , Output a standard voltage with strong driving ability to track the input signal. The sensor is also equipped with a DC / DC converter inside, from the auxiliary power + E to extract energy for the input circuit. And provides the sensor output termination to follow-up equipment such as high-speed A / D circuit, the signal is controlled by the computer sampling, processing, and the application of the corresponding transfer function example.
