Current Sensor Module WCM7800 Introduction

The WCM7800 consists of a current sensor, temperature sensor, a very high accuracy A/D converter and digital signal output of current.
The unique spring structure of WCM7800 can improve the tightness on both sides of the iron core, making measurement more stable and reducing the influence of structural opening and closing tolerances. Users can just use system’s own electric wire by pass it through this hole to measure passing current without breaking original system, user’s MCU can get the real data from DATA pin.
The WCM7800 provides temperature calibration of the internal current sensor and accurately measures the current of AC 50 / 60Hz and DC at temperature from -20˚C~70˚C. The WCM7800 also offers solutions for true RMS current measurement of various loads.
