WBI414F31 (AC Current Sensor, 4–20mA / 0–20mA Output) converts AC input current into a load-independent DC output signal of 4–20 mA. The AC Current Sensor adopts the principle of electromagnetic isolation for real-time measurement of AC current from the power grid or electrical circuits.
The AC Current Sensor offers advantages such as full galvanic isolation between input, output, and auxiliary power, high accuracy, low temperature drift, and a wide operating temperature range.
Advantages:
* 26,000 square meters of dust-free workshop
* 30 years of experience
*Application in high-speed railways
* ISO, EMC, and ETC certified
Applications:
* Current measurement
* Automatic monitoring and control
* Electrical signal detection and modulation
* Data acquisition
