Current Sensor Module WCM1700 Introduction

Current Sensor Module WCM1700 provides economical and precise solution for both AC and DC current sensing in industrial, commercial and communications systems.
The WCM1700 consists of a current sensor, temperature sensor, a very high accuracy A/D converter and digital signal output of current. The WCM1700 includes a current sensor with a diameter 9mm hole, 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 WCM1700 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 WCM1700 also offers solutions for true RMS current measurement of various loads.
