Current Sensor Module WCM2705 Introduction
Current Sensor Module WCM2705 provides economical and precise solution for both AC and DC current sensing in industrial, commercial and communications systems. The WCM2705 consists of a current sensor, temperature sensor, a very high accuracy A/D converter and digital signal output of current. The WCM2705 includes a current path with 8.3mΩ typical internal conductor resistance. This extremely low resistance can effectively reduce power loss, operating temperature and increase the reliability greatly, user’s
MCU can get the real data from DATA pin.
The WCM2705 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 WCM2705 also offers solutions for true RMS current measurement of various loads.
