The Winson WCM1600 provides economical and precise solution for both AC and DC current sensing in industrial, commercial and communications systems. The WCM1600 consists of a current sensor, temperature sensor, a very high accuracy A/D converter and digital signal output of current. The WCM1600 includes a current sensor with a diameter 9mm hole, users can just use systems own electric wire by pass it through this hole to measure passing current without breaking original system, users MCU can get the real data from DATA pin.
The WCM1600 provides temperature calibration of the internal current sensor and accurately measures the current of AC 50 / 60Hz and DC at temperature from -20C~70C. The WCM1600 also offers solutions for true RMS current measurement of various loads.
