Dc Current Sensor With Analog Output WBI344U01-S

Dc Current Sensor With Analog Output WBI344U01-S

WBI344U01-S adopts the principle of modulation and demodulation isolation to measure the DC current in the power grid or circuit in real time, and convert it into a standard DC current output; it has the characteristics of high precision, high isolation, low drift, and wide temperature range. Input and output circuits are completely isolated, and all output signals share the same ground with the power supply, which can be directly connected with various types of A/D converters to form a centralized data acquisition system. This product is suitable for real-time detection of power systems, post and telecommunications systems, railway monitoring systems, etc.
